caddice fly
Noun: A small, moth-like insect belonging to the order Trichoptera. Adult caddice flies are characterized by having two pairs of hairy, membranous wings that are held roof-like over the body when at rest. They are most notable for their aquatic larval stage, during which many species build portable protective cases from silk and materials like sand, twigs, or leaves.
The term "caddice fly" refers specifically to the adult insect. It is used in entomological and ecological contexts to describe these insects and distinguish them from similar ones, like moths. - The biologist studied the caddice fly to understand its role in the freshwater ecosystem. - Anglers often use artificial flies that mimic the caddice fly to catch trout.
- Indicator Species: In environmental science, the presence or absence of caddice fly larvae is used as a bioindicator to assess water quality and the health of aquatic habitats.
- In Fly Fishing: The term is often shortened to "caddis" in angling terminology. Different life stages (larva, pupa, adult) are imitated with specific artificial flies known as "caddis patterns."
- Caddisfly: An alternative, and more common, single-word spelling.
- Caddis: A common shortened form, especially used in fly fishing.
- Caddice Worm / Caddis Worm: Refers to the aquatic larval stage, not the adult fly.
- Trichoptera: The scientific order name for all caddice flies.
- Sedge fly (primarily British English, used in fly fishing contexts).
The word "caddice fly" has no other distinct meanings. Its definition is specific to this group of insects. The key distinguishing feature from true moths (order Lepidoptera) is the hairy (not scaly) wings and the entirely aquatic larval development.
