I moved to a new city in west India last year and I've since, on several occasions, seen this insect on walls and it's usually climbing using its head. It has a greyish long shell and moves in a very wobbly way. I've asked people in the locality if they know what that insect is, but no one has a clue. And my curiosity is piqued everytime I see it and I really want to know what it is.

Here are two closeup images:

I have a video as well but I don't know how to share it here.

I was suggested that this question is a possible duplicate of: What insect is this? (India)

The insect in my case is probably much smaller and has a plain grey shell (as opposed to building a shell from material lying around, which would most probably be different every time). I don't explicitly see any legs although there may be.

I want a definitive answer as to what moth it is or if it is one or not.

That's a plaster bagworm [ ] :)

CLOSED: can anyone please tell me what kind of bug this is please

this hard shell little black thing has white web coming out of it. does anyone know what it is and how to get rid off it it has eat holes in almost all off my angel trumpets and they have been treated with merit( marathon1%) both granular and spray.

wow have never seen anything like that on my brugs in all the 12 years I have been growing them

Please forgive me - but are you sure that it isn't something else that is eating the holes in the leaves there -?-

My inquiry, is merely because the lil 'hard shell black things' look to be some other type of seed/s that may have distributed themselves over onto your angel trumpet leaves.

Do you (or perhaps a neighbor) .. happen to have any type of Milkweed plants -?- The milkweed seed have a 'webby' tail attached, and it looks like may be the milkweed seed that have also gotten a bit of a drenching from rain, etc. ..

It is difficult to tell such, from an image displayed on a computer monitor screen (along with my poor eyesight) .. but is only a compelling hunch.

yes i am sure they are not seeds they are on the front and back of the leaves and they are stuck i have to pull them off. and they are right where the holes are. i have about 60 angel trumpets and have been raising them for 3 years. i have seen alot of bugs on them but never like this. it did start on a new plant i order on ebay but i didn't see it on it when i planted it. maybe it was in the dirt. it is not just a few places it is on almost all of them. some it's just starting on and some are eat up. i hope someone knows what they are. thanks

boy, that is a mystery. bt wouldn't work, i don't think. maybe a tablespoon of molasses mixed in a quart sprayer of water. it leaves a bad taste in the mouths of some bugs, worms, beetles, whatever the heck it is!

We have the exact same bugs in our garden! I can not figure out what the heck they are and all they do is just multiply. the are even on the sidewalk. They are eating the leaves too!

Send the picture to your County Agricultural Agent's office. Maybe they can at least id the bug.
Sure does look like Milkweed or other fluffy seed after a rain.

Why Aren't Insects Human-Size?

Director Edgar Wright, known for movies such as "Shaun of the Dead," announced earlier this week he would be making a movie about Ant-Man, a comic superhero who can shrink to the size of an ant and communicate with his formic brethren, according to the news site Grantland. If it's anything like the comic, it will also feature ants as big as humans, which got us thinking: Could ants be as big as people? And why aren't insects bigger than they are?

The short answer is, researchers don't know exactly, although there are several hypotheses as to why insects and other arthropods don't get bigger, said insect physiologist Jon Harrison, at Arizona State University in Tempe.

The first hypothesis is that insects' exoskeletons may not be strong enough to allow them to get much bigger &mdash that they'd have to become impossibly thick. Harrison learned this theory as an established fact during his training, but little experimental evidence to support the idea exists, he said. The only study to look at this question found that larger arthropods don't have thicker exoskeletons, he said. "So there's no direct evidence for this," he said.

Because exoskeletons are rigid, insects need to molt as they grow, shedding the old skin and growing a new one. Scientists have suggested this vulnerable time puts a ceiling on size: Larger animals, particularly those without protective skeletons, would make for more attractive meals to a predator. "The bigger you get, the more of a tasty vulnerable package you are," goes the thinking, Harrison said.

A related theory suggests being larger makes you a more attractive meal, whether molting or not. One study found that the size of ancient flies declined as birds evolved, suggesting smaller creatures were better able to avoid hungry raptors and pass on their genes.

Another possibility: Insects have open circulatory systems, where blood and bodily fluids aren't bound up in vessels, as is the case with most vertebrates. This makes it more difficult to move blood throughout a large body, as circulation would be hampered by gravity, which pulls blood downward.

Not enough oxgyen

Perhaps the most plausible hypothesis, and one that Harrison has studied extensively, is the role played by oxygen. Insects "breathe" via tiny tubes called trachea, which passively transport oxygen from the atmosphere to bodily cells. Once insects reach a certain size, the theory goes, the insect will require more oxygen than can be shuttled through its trachea.

Support for this theory comes from the fact that about 300 million years ago, many insects were much larger than they are today. There were, for example, dragonflies the size of hawks, with wingspans of about 6 feet (1.8 meters), and ants the size of hummingbirds. At this time, the oxygen content in the atmosphere was about 35 percent, versus 21 percent today.

Harrison's work has shown that almost all insects get smaller if you rear them in low oxygen conditions many of them get bigger when you give them more oxygen. Certain species can get about 20 percent bigger in a single generation when given more oxygen, he said.

Bulky insects also seem to need more trachea. "If you extrapolate that out with a much bigger insect, perhaps there'd be nothing left but trachea," he said. And there's only so much room &mdash an animal needs room for other organs, muscles and the like.

But that hasn't been proven, and scientists don't understand exactly why insects aren't bigger, or more broadly, the biological basis for controlling body size. There are many more questions than answers, he said.

Okay, but ants as big as humans? "I'm not willing to say it couldn't happen," he said.


Also known as the roly-poly bug, the pillbug is most active at night. This gray or brown creature may have "bug" in its name, but it isn't an insect at all. With body segments resembling armored plates, the pillbug is related to lobsters and crabs, and it's the only crustacean adapted to spend its life out of water. Though terrestrial, it stays in damp environments and breathes through gills. 2 This pest, a cousin of the sowbug, is technically a decomposer that eats dead plant material, but it can also be guilty of enjoying summer feasts of garden seedlings and soft fruits and vegetables.

  • Designation: nuisance
  • Remedy: Reduce or eliminate moist piles of leaves, wood and organic debris. Protect fruit and vegetable plants by growing them in above-ground containers or pots. For in-ground gardens, cover the soil surrounding plants with black plastic. The plastic will get too hot in the summer for pillbugs to walk on. Like earwigs, these pests can also be trapped under newspapers at night. In the morning, just scoop them up and drown them in soapy water. For quick control, apply Amdro Kills Ants & Spiders, which can kill up to 50 insects and spiders.

3. Damsel Bugs

Damsel bugs are from the Nabidae family of insects. They sound dainty, don&rsquot they? Damsel bugs got their name because of the way they hold their front legs up in the air- as if holding up the hem of a skirt. (Yeah, I don&rsquot know. I thought it was a stretch too.) They range from green to tan to brown and have veined wings over their backs.

I&rsquoll spare you the gory details, but remember those cute front legs that are supposedly holding up a skirt? Nope, those legs grasp and hold prey.

The good news is their prey are common garden pests such as insect eggs, aphids, mites, and even small caterpillars.

Damsel bugs are what&rsquos known as a &ldquogeneralist predator,&rdquo which basically means they aren&rsquot picky eaters. Damsel bugs will also eat other predatorial insects such as the minute pirate bug or assassin bugs. And if the prey is scarce, they will eat each other.

While you can&rsquot buy Damsel bugs, you can encourage them to hang out in your garden. Discontinue the use of pesticides and provide a diverse variety of plants to entice them to hang around.

What Is a Horned Nosed Beetle?

Seems like a stupid question, but hey, I have to start somewhere. A horned nosed beetle is a medium-sized dark brown bug that lives just below the surface. He (or she) has a body armored with a super hard dome shaped shell and a separate shelled head. Most of these brown bugs don’t have horns, but a few do. They have three little, but very sharp horns, protruding from (what it appears to me to be) the top of their heads. Useless opinion: I don’t know why they are called horned nosed beetles as the horns are clearly on top of their heads. Maybe the name horned “headed” beetles doesn’t roll off the tongue well or just “horned beetles” wasn’t specific enough. Doesn’t matter much I guess, so never mind. These not so cute little guys burrow under the soil and that’s a problem for above ground pools. It’s a problem for them too if they get caught under one.

I Have Something Sharp Under My Pool Liner. How Do I Tell If It’s a Horned Nosed Beetle?

It can be hard to tell. The last call I got for one under a liner was difficult even for me to determine. Lucky for me, the pool owner clipped off one of the horns sticking through the bottom of his pool before I got there thinking it was a piece of wire. I thought it was a piece of wire too when I dove down to look at it. When he brought out the saved horn piece, I was relieved knowing it wasn’t something I left in the ground and it was, in fact a horned nosed beetle. Not my fault. Whew!

I couldn’t determine then if it were a beetle, but there are two ways you can tell sometimes. One is if you feel three little sharp points that make up a kind of a triangle, it’s probably a beetle. Also, if there is a small rut or trail leading to the sharp spot, it’s probably a beetle. Sometimes the beetle will have only one or two horns and won’t leave any kind of a trail at all so that doesn’t help. Also, beetles don’t usually make it very far before they try to surface so they will poke through the liner only about a foot or so from the pool wall.

OK, So It Is a Horned Nosed Beetle. What Do I Do Now?

So you’ve got this hard shelled bug trapped under your pool liner with his horns making one or two or three small holes in it. What now? Well, first off, if you do yoga, hug trees, and trap spiders inside your house so you can put them outside, cover your ears. The beetle is dead! By the time you feel his horns, he is long gone. Some of you won’t believe me and will try to save him. That’s cool and good for you. Here are two ways to fix your pool:

For trying to save him (not recommended):

  1. Run to the store and get an underwater vinyl patch kit.
  2. Using a sharp utility blade, go down to where the beetle is and make a slice in the liner directly over him. Make the slice only big enough to get him out. Don’t worry about cutting the beetle. He has a badass shell.
  3. With the knife or a fork or something, pry him out from under the liner and bring him to the surface.
  4. If he eventually moves around, congratulations. You saved a beetle. Now you can get an I-saved-a-horned-nosed-beetle sticker for your Prius.
  5. Now patch the big hole you just cut following the kit’s directions and you’re done.

The meat eater’s way (recommended):

  1. Get an underwater vinyl patch kit.
  2. Go down with a hammer to where the beetle has made a hole in your liner.
  3. Gently tap the beetle’s protruding body and horns flat so that it is level with the rest of the smooth pool bottom. If gentle taps won’t get him down, hammer him down hard!
  4. Now patch the hole made by the horn and you’re done.

Preventing Horned Nosed Beetles From Getting Under Your Pool Liner

It is really rare for horned nosed beetles to make holes in above ground pool bottoms. Most areas don’t have them and even if your yard has them, it doesn’t mean they will go under your pool. I’d estimate that maybe one in every 500 to a 1000 pools will have this issue so it’s not worth doing anything.

If you know you have these horny beetles in your yard and you are getting a pool, you could get one of the bottom materials I mentioned at the beginning, but I wouldn’t even do that. I would instead wait and see if it’s a problem and just fix it when it happens. It’s no big deal really.

Biology Unit 3

- Ecto- means "outside" or "outer." Cells of the ectoderm form the skin, nerves, and sense organs (like ears and eyes).

-Animal cells are surrounded by a cell membrane and do not have cell walls.

-Animals are composed of specialized cells that form tissues, organs, and organ systems.

-Typically, animals reproduce sexually.

-Animals are heterotrophs, meaning they must obtain energy by ingesting food.

-All animals, in one or all stages of their lifetime, are capable of motion.

- Cnidaria: This phylum includes the simplest animals with symmetry. Cnidarians are radially symmetric and have two germ layers. Jellyfishes, sea fans, and sea anemones are members of phylum Cnidaria.

-Arthropoda: This phylum includes bilaterally symmetric, segmented animals with exoskeletons and jointed appendages, such as insects, spiders, and scorpions.

-Nematoda: This phylum contains nonsegmented worms with pseudocoeloms.

-Platyhelminthes: This phylum contains the simplest animals with three germ layers. These flattened worms are bilaterally symmetrical, nonsegmented, and they have no coelom.

-Annelida: This phylum includes segmented worms with a true coelom, such as earthworms, leeches, and some marine worms.

-Mollusca: This phylum includes soft-bodied animals that have an internal or external shell, such as snails, slugs, and clams.

-Echinodermata: This phylum contains radially symmetrical, deuterostomes with spiny skin and an internal skeleton, such as sea stars, sea urchins, and sand dollars. Because they are deuterostomes, echinoderms are considered to be closer relatives to chordates than the other invertebrates.

The Difference Between a Cocoon and an Egg Case

Technically, moths spin cocoons and praying mantis spin egg cases, but for the sake of the average backyard gardener just looking at egg sacs hanging from trees in the garden and wondering if they should kill them or leave them alone, I’m sticking with “identifying good bugs from bad by their cocoons” for this article.

A Good Bug = Helpful to the Garden

There’s really no such thing as a good bug or a bad bug. Most people consider ‘good bugs’ those that are helpful to the garden or at least won’t hurt anything. ‘Bad bugs’ are those that harm plants, clothing (if indoors), or pose other threats.

Please note : I am asking all of my students to buy a textbook and lab manual as evidence you have prepared for the course. The cost is relatively low (certainly less than taking the class again), and you can sell the text back later if you choose. You may also get various versions of the text, but realize that the syllabus and study guides, exams, etc. were created with a hard copy of the text in mind. Many examples questions, and even chapter titles, numbers, etc. in the syllabus are all based on this text hard copy. If you do not have a hard copy, or you use an alternative text you can still do very well in the course. You may struggle with some of the readings, example questions, etc. as the text determines the lectures, lectures help design the tests and I think you can see now why I am encouraging hard copy of the text to help ensure we are all working from the same platform. Also…if you find a suitable version of the text, but there is no physiology element in the title, do not panic! This text will work and I will make available chapters on these physiology subjects once we get the class establish.

As for the lab manual, I also want you to go to the College of the Canyons Bookstore and order a copy. It costs just a few dollars, and the bookstore will mail it (and your text?) to you for free. So please plan ahead and get these ordered. I will offer more insights as to why I am so adamant as to why students should purchase a textbook, but leave this topic to later meetings in Zoom with one final thought.

Despite decades of teaching science and immersing myself in new technologies of science and teaching of science, I must say I am not enamored with many advancements in teaching technology. I am a firm believer that less is more. Get a textbook, read it, come to lectures and take notes, discuss what we review, and this class is VERY basic. The amount of science that can be conveyed is enormous and lectures can literally teach “rocket science”, but they are based on a crucial assumption. Students need to come to class prepared. So, in the new normal of everything on-line please take a minute to look to the basics. Look past the internet, Google, PowerPoints, recorded lectures, heck, even colored chalk. A lecture can be phenomenal way to learn science and so use this coming fall 2020 to broaden your horizons and get back to basics. Get a book, read ahead, take detailed notes, engage the lecture (and LAB!) and get a first-class education in Introductory Biology Lecture and Lab. So follow me into the wilderness that is Biology 100. Your tour guide and Professor…Jim Wolf

Bugged Out

A neighbor told me what she does to rid her apartment of roaches, and I decided to try it. As one exterminator opined in a previous post, those of us who have roaches as well as bed bugs have found that foggers designed to kill roaches end up irritating bed bugs and scattering them further throughout your home. This does not kill or even harm the bed bugs, but instead makes it that much harder to ensure that you've killed all the bed bugs in your home when you do go after them.

Obviously, an effective roach-killing method that won't affect bed bugs in any way (until I'm ready to kill them) interested me, as I do have both roaches as well as bed bugs. So here is what my neighbor told me to do:

Boil some eggs, then remove the shell and mash up the insides (yolk and white) with a fork. Then add a generous amount of boric acid onto the mashed egg. Using the same fork, lay a few pieces of this mixture onto the kitchen sink, behind the toilet bowl or anywhere else in your home you've seen roaches.

The beauty of this, of course, is that it effectively kills the roaches (and it does, I tried it out last week) without disturbing the bed bugs. That way the bed bug will never see it coming when you actually do go after them.

I advise anyone to try this hard-boiled egg/boric acid mixture in their homes as an alternative to roach fogger which, as I've witnessed firsthand and many people have told me, will only irritate and scatter the bed bugs.

Good luck, and happy hunting!


I've heard that boric acid is helpful in getting rid of roaches, but I'm hesitant to use it because I have an older dog with some health issues. Any idea as to the toxicity to animals?

Also, I was wondering why egg needs to be mixed with the boric acid - does that attract the bugs? Some accounts I've read where boric acid was used alone.

I only have a "few" bugs in my house (that show themselves, at least) but I want to be rid of them once and for all.

Animals won't eat the boric acid. I've got kittens and they completely ignore the stuff. Since it's in a paste and you apply it to areas like baseboards in the kitchen and behind appliances, you don't have to worry about fumes.

I've used it before and it works well, but it's not so great on it's own if you have a full blown infestation. It does, however, work well at maintaining a bug free space after spraying. Since you don't have that many, I'd recommend trying it.
