larva crawling Thyridopteryx ephemeraeformis, evergreen bagworm Thyridopteryx ephemeraeformis, evergreen bagworm. The evergreen bagworm (Thyridopteryx ephemeraeformis), commonly known as bagworm, eastern bagworm, common bagworm, common basket worm, or North American bagworm, is a moth that spins its cocoon in its larval life, decorating it with bits of plant material from the trees on which it ...
Once the caterpillars reach maturity, they spin large brown cocoons longways on trees or wooden structures. They will then emerge as adults in the first two weeks of seasonally warm weather in early summer. Hyalophora cecropia moths are univoltine, having only one generation per year. Upon reaching adulthood, their size is variable.
The rear wings are reddish brown. [5] Eggs are green, elongated and cone shaped, with a flattened base and distinct longitudinal ribs. Caterpillars are reddish to greenish brown, with dark dorsal lines and a yellow side band, the head is relatively small and brown. Cocoons are red brown or green. [5]

Mud dauber (or "mud wasp") is a name commonly applied to a number of wasps from either the family Sphecidae or Crabronidae which build their nests from mud; this excludes members of the family Vespidae (especially the subfamily Eumeninae), which are instead referred to as "potter wasps".
Immediately following the serpentine stage, the mine broadens to form a large, somewhat inflated blotch. Full-grown larvae drop to the ground and burrow into the soil. Here, they create a relatively tough oval cocoon of silk and small particles of soil. The larvae have a dark brown body and a pale brown to light yellow head.
An antlion cocoon on the side of a house. When the larva attains its maximum size, it pupates and undergoes metamorphosis. [15] It makes a globular cocoon of sand or other local substrate stuck together with fine silk spun from a slender spinneret at the rear end of the body. The cocoon may be buried several centimetres deep in sand.
Once they are ready to pupate, the grubs spin reddish-brown cocoons in one of the main mining halls they created as larvae. They remain in these cocoons until the second week of June where they then emerge as adults. [1] The new adults then continue on their journey to eat yet more leaves until mid or late July.
