A cocoon is a protective casing, usually made of silk. This casing protects the larval, or immature stage, of an insect from the elements, such as extreme temperatures. Inside the cocoon, the larva, which is often wormlike, will undergo metamorphosis and emerge as an adult, a process common among insects and other arthropods.
Adult fleaswhich pet owners may see on their dogs and cats, can lay up to 50 eggs a day. After hatching, these eggs produce worm-like larvae. Inside the home, these larvae may be found in carpet or other areas frequented by pets. The larvae form cocoons, and in weeks will transform into adult fleas. These cocoons are nearly impossible to see. Butterflies and moths are perhaps the most commonly known insects that build cocoons.
Their larvae, which are caterpillars, are voracious eaters.
Caterpillars spin silk, and this silk is used to form the cocoon for the pupal stage of development — the final stage before adulthood. Some moths, such as the clothes mothmay find their way into homes.how to control pests in your home, small larvae like bugs in house, small flat bugs in house
These moths feed on common household items, such as fibers in clothes and grains or other foods in the kitchen. If necessary, these moths may form cocoons and pupate in your house.
A pest control professiona l can help identify the cocoon and the species of moth that created it. These insects resemble moths, and they spend most of their lives in or near bodies of water like lakes, rivers and ponds. The larval stage of these insects lasts up to two years, during which they feed on algae or other small organisms found in the water in which they live. Larval caddisflies spin silk and use this material to make cocoons or casings around twigs and other particles in the water, like sand and gravel.
Typically, caddisflies pupate from the winter through the early spring. Some species of parasitic wasps attack hosts and use these host insects as nutrients for their young throughout development.
The stage at which the wasp attacks varies with species, some attacking eggs, others choosing larvae or adults. Common host insects include aphids, caterpillars, sawflies, beetles and flies.

They are attached to walls and to the ceiling, but sometimes they fall off. Inside the structure there is a small worm that can come out at both ends alternatingly. It can then hold on to the ground to move the cocoon around.
They are said to feed on paper. This little dude is not a Caddisfly, but a true moth, Tinea pellionellaa case making clothing moth. Confusing because they do resemble caddisfly larvae cocoons more so than those of their own family Tineidae. Sort blurb Here :. The case in the above image is covered with fine sand and debris, and superficially resembles a caddisfly case. When crawling, the larva's head, thorax, and three pairs of legs protrude out of the case, and drag it along. According to Internet sources, the larva feeds on a variety of material, including hair, fur, silk, felt, feathers, woolen clothing, upholstered furniture and carpets.
It apparently prefers darkness and soiled clothing, and is not fond of synthetic fabrics, such as nylon and polyesters. This is probably caterpillar of one of the moth species from family Psychidae. They larvae looks like Trichoptera larvae and builds similar cases out of silk and material found in nearby surroundings.
In contrast to TrichopteraPsychidae caterpillars don't live in water, and some of them inhabit stones and walls, where they feed on lichens. This is a wild stab in the dark, so downvote me as you see fit: Caddis fly larvae Insect Order Trichoptera.
Cocoon Bugs are Case Bearing Moth Larvae
I thought caddis larvae were aquatic though. If you are looking for information on Coronaviruses, we have prepared this FAQ with information on what is on topic on this site and links to some reputable external resources.The case of the plaster bagworm is somewhat similar to a watermelon or pumpkin seed in its shape, size, and flatness.
It can look like an empty case or shell. Slit-like openings are located at each end. The entire thing is about half an inch long.
The openings at the end allow the larvae to move and to eat. Plaster bagworms are a close relative of the clothes moth. They eat spiderwebs, wool, and the discarded larval cases of members of its own species. The reason plaster bagworms are common Florida pests is because they like the high humidity found here. A good way to keep them away is to keep your air conditioner on and your house cool.
Obviously getting rid of spiderwebs is a 1 priority, since that is a favorite meal of the plaster bagworm. In its larval stage, the plaster bagworm has three set of legs as well as false legs. A mature bagworm caterpillar is about a quarter of an inch long. Its body is mostly white, but its head is brown.

It's light in color, and oval. Our cedar trees and evergreen bushes have tons of chysalises made from their needles. Can you help me identify them?
Cristina Nott Mar I have cocoons all over my apricot tree which is starting to lose its leaves.
4 Types of Pests That Build Cocoons
The cocoons are made up of several dead leaves all stuck together. I had noticed that some of the leaves were being eaten from early summer, but the fruit wasn't damaged so I didn't worry about them.
I never saw a caterpillar. I do have borers that cause some problems. I have to saw off branches a couple of times a year to keep the tree looking healthy.
I Don't know if these two things are related. This is a big apricot tree that bears an enormous amount of fruit. Patricia Burkhalter Jul I found many brown, wood-like cocoons attached to cedar branches and my weeping willow tree branches. Recently, I've noticed the tops of the cedar trees appear to be dying.
How do I successfully remove the cocoons and revive the trees? Live in NW Iowa. What could they be? Amber Frederick May I found a "clay pot" looking cocoon on my bonsai tree can you identify it?
I didn't see it in your pics. Somebody May I found a cocoon that looks like a piece of wood and is rough but it is soft and in a cylinder shape that comes to a point, and I do not know what it is? Melissa Geib Oct Found a picture of a possible cocoon.By fakenameApril 7, in Pattaya Forum. Just wondering if someone knows the name of the insects, that attach themselves to the ceilings and walls of homes.
This morning just noticed that there were a hundred or more on the walls. They look like a worm, but then make a cocoon, which usually hangs by a thread, like a spider web. I see them all the time, but today, there were more than normal. I tried to Google something up, but just too many to go through. I guess they are harmless, but would just like to be on a first name bases with them, since they are living in my home. They are harmless.
I pick them off the wall every time I spot one, otherwise they continue on and attach themselves to the ceiling, Where they or the remains of whatever process is going on remain forever! I hope someone knows more, as I've often wondered what is going on with them.
Do they turn into some kind of moth? I had one that opened and turned into Stephan Harper and then sold Canada's Oil sands to the Chinese. They are cocoons for a small moth called casebearer moth, there has been other posts about them in the past. They're generally harmless but a nuisance as they multiply quickly. Often they hide behind pictures or furniture. I usually just pick them off whenever I see them. That is strange.
I have seen and had the cocoons, many of them, in different locations, but never noticed that kind of moth around. Also the cocoons don't seem to look exactly like that - no "head" so visible - but that probably is due to higher quality in the image on the picture than on my eyes. I think Phil is right, but I also have never seen any moths, so dont know what they eat, and where they lay their eggs. I guess the head only pops out at certain times, when they are on the move.
The cocoon is left behind after the moth is gone, so obviously there you will not see any "head", but if you find a live one just hold it for a moment and you'll see the head move. I've had silverfish in the boot of my car here in Thailand I think they liked the damp carpet fixed the leak and got rid of carpet.
We have loads of these buggers in the house, we have mossy screens everywhere and are always careful about using them yet we have these moth things hanging from the ceilings in most of the rooms, if you pick them off the wall and place them on a flat surface then after a while they start moving.Green Pest Services Florida.
Have you noticed small greyish to white colored bugs hanging on your walls or ceiling? Or maybe it looks like some kind of egg sac? What you are likely seeing is a cocoon-like case, with an insect hidden inside. The common name for these creatures is a Plaster Bagworm, however, it is more etymologically accurate to refer to them as Household Case Bearers Phereoeca uterella.
Dust Worms are another common name for these creatures. Despite ultimately transforming into a moth, it is not typical to have significant numbers of moths visibly flying about the house.
If this is the case, it is more likely you may have an infestation of Indian Meal Moths. Like people, insects have basic needs such as food and shelter, that must be met in order to survive. Their diet consists of old spider webs, dead insects, and even human hair. Part of the reason these insects are found stuck to walls and ceilings is that they have climbed up there to be closer to the cobwebs they feed on.
It's very common to find Plaster Bagworms and Household Casebearers attached to the exterior stucco, vinyl or wood siding of homes as well. Because both their diet and the material used to create their cocoon is basically tiny bits of organic material, thorough and consistent cleaning can remove both the food and shelter they need to survive and result in a decreased population.
This, however, can be a bit difficult in areas such as garages, carports, patio, and lanai areas. Nevertheless, sweeping down cobwebs, and blowing out accumulated debris in garages and porches will help prevent a thriving Casebearer population. Another good tip for preventing Plaster Bagworms is to reduce outside lighting. Ultimately, these little creatures are moths. Moths are notoriously attracted to porch lights.
If moths are attached by a light left on in the garage, or a security light on the side of the house, you are attracting them to your home. It is ultimately these adult female moths that will lay the eggs that eventually turn into the annoying little egg sac-like creature stuck to your ceiling. Obviously, there is little that can be done in this regard in outside areas. They are certainly capable of surviving inside homes. Plaster Bagworm populations will be higher in homes where the inside temperature is kept above 80 degrees.Photo By: Courtesy of P.

First, these helpful predators have been active in your yard already. Also, you have a great chance of getting their help again in the coming season when the babies emerge. Butterflies may help a little with pollination, but the greatest benefit of their presence is the color and movement they bring to the garden.
See its recently vacated chrysalis to the right? The difference between a chrysalis and a cocoon? Butterflies emerge from a chrysalis, which is made of hardened protein. Many moths come out of cocoons, which are spun from silk. The eastern tent caterpillar camps out in the crotches of trees and shrubs in spring. Fall webworms pitch their tents over branch tips or small clusters of branches in fall. Garden spiders are notorious for their broad webs that are especially ornate when morning dew has condensed on the strands.
These webs are a welcome site, as a sign that another critter is on the gardener's team. Garden spiders gobble up thousands of potentially harmful insects in their lifetime including flies, mosquitos and aphids. This web is not a welcome site. Spider mites thrive on the juices of your precious garden plants. Not all bug killers are created equal. If you detect a spider mite infestation, use a miticide that specifically targets these pests. Squash vine borers chew their way through the leaves and stems of summer and winter squash.
Look for wilted leaves with mushy stems as the major indicators.
