Caddisfly larvae (Order Trichoptera)

Key features:
- "worm-like" appearance
- 6 legs near head
- small tail hooks
- size range: 1/4" - 3/4"
- may be found in case

Caddisfly larvae can often be found on the undersides of stones, protected by a collection of small pieces of stone, shells, or other materials which are held together by an adhesive substance that caddisfly larvae secrete. They may also be found in cylindrical cases which they make and wear for protection. They will retract into this case when threatened or startled. Body color of these larvae varies from yellow and green to brown. Note: These larvae tend to curl up slightly (as pictured) when placed on a flat surface.
