Where can I find Trichoptera?
- The caddisflies, or order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults.
- The aquatic larvae are found in a wide variety of habitats such as streams, rivers, lakes, ponds, spring seeps and temporary waters (vernal pools).
What family are caddisflies?
Caddisflies (Trichoptera) The order Trichoptera (caddisflies) is a group of holometabolous insects closely related to butterflies (Lepidoptera). It includes approximately 15,000 extant species within 49 families and approximately 600 genera (Holzenthal et al., 2011, 2015).
How do you identify a caddisflies?
Distinguishing taxonomic features Caddisflies are mothlike insects with two pairs of hairy wings that are folded rooflike over the abdomen at rest. Antennae are long and many jointed with a large basal segment. Large compound eyes are present, whereas simple eyes (ocelli) either number three or are absent.
What would be the correct classification of a Caddisfly?
Trichoptera
Caddisflies/Scientific names
Where are caddisflies found?
Adult caddisflies are terrestrial, while larvae are aquatic and can be found in lakes, rivers, streams and other freshwater sources. Although they live on land, adult caddisflies typically inhabit areas near freshwater sources in order to ease breeding processes.
Do all caddisflies make cases?
Caddisfly larvae are most diverse in cool, flowing water, but have invaded a wide range of habitats. They are known to construct cases out of silk and various other materials, for shelter. Most caddisfly larvae can be found in benthic habitats in temperate lakes, streams, and ponds.
What are characteristics of trichoptera?
The body and wings are clothed with long silky hairs (setae) — a distinctive characteristic of the order. In flight, the hind wings are coupled to the front wings by specially curved hairs. At rest the wings are held tent-like over the abdomen. Many caddisflies have reduced or vestigal mouthparts.
What do trichoptera feed on?
Free-living caddisfly larvae. (order Trichoptera, family Rhyacophilidae) Feeding: Predators feeding on various insect larvae and other small invertebrates.
What are characteristics of Trichoptera?
What do caddisflies use their cases for?
Caddisflies build cases that function as protective armor against predators out of a variety of materials in their environment. The results of our study demonstrate that the presence of any case, constructed from even relatively weak materials, provides protection from at least some predators.
How do trichoptera feed?
(order Trichoptera, family Polycentropodidae) Feeding: Filterers/predators – larvae feed on organic debris and invertebrates that get caught in the net. Net may be equipped with silken threads extending the entrance.
What is a caddisfly classified as?
Caddisflies (Order: Trichoptera) The Trichoptera, or Caddisflies, are an order of insects, somewhat related to moths, and of which there are just under 200 species in the British Isles. The name means ‘hairy-winged’, and indeed they differ from moths in having hairs rather than scales on their wings, amongst other differences.
What is the scientific name of the order Trichoptera?
The name of the order “Trichoptera” derives from the Greek: θρίξ (thrix, “hair”), genitive trichos + πτερόν (pteron, “wing”), and refers to the fact that the wings of these insects are bristly.
Where do case building caddisfly larvae live?
Case-building caddisfly larvae (order Trichoptera) Habitat: Case-building larvae can be found in variety of ecosystems from small ponds and streams to large lakes and rivers. Movement: Climbers or crawlers resembling hermit crabs. Some small species are able to swim.
Are caddisflies nocturnal or diurnal?
The order Trichoptera (caddisflies) is another likely descendant of the Mecopteran lineage. Adults are mostly nocturnal, weak-flying insects that are often attracted to lights. During the day, they hide in cool, moist environments such as the vegetation along river banks.
