Have you ever seen one of these weirdos? They are so weird man!  I have sometimes seen them hooked on the outside stucco wall and thought what the heck are those weird sand leaves?  Then all of a sudden a little worm head comes out and moves the whole sand cocoon with it.  What!


The Household Casebearer, Phereoeca uterella:

From the awesome site What’s That Bug:  “Habitat  Larval cases can be found on wool rugs and wool carpets, hanging on curtains, or under buildings, hanging from subflooring, joists, sills and foundations; also found on exterior of buildings in shaded places, under farm sheds, under lawn furniture, on stored farm machinery, and on tree trunks.  Food  larvae feed on old spider webs; may also eat woolen goods of all kinds if the opportunity arises.

The larval case is silk-lined inside and open at both ends. The case is constructed by the earliest larval stage (1st instar) before it hatches, and is enlarged by each successive instar. In constructing the case, the larva secretes silk to build an arch attached at both ends to the substrate. Very small particles of sand, soil, iron rust, insect droppings, arthropod remains, hairs and other fibers are added on the outside. The inside of the arch is lined exclusively by silk, and is gradually extended to form a tunnel, while the larva stays inside. The tunnel is closed beneath by the larva to form a tube free from the substrate, and open at both ends. After the first case is completed, the larva starts moving around, pulling its case behind. With each molt, the larva enlarges its case. Later cases are flattened and widest in the middle, allowing the larva to turn around inside.
