Aquatic emergence traps are cage-like or tent-like structures used to capture aquatic insects such as chironomids, caddisflies, mosquitoes, and odonates upon their transition from aquatic nymphs to terrestrial adults.
en.wikipedia.org The species diet consists mostly of snails and insects (caddisflies, midges, and blackflies).
en.wikipedia.org The study found the banded darter prefers chironomids over the mayflies (ephemeropterans) or caddisflies (trichopterans), and the fish fed more during the day than they did at night.
en.wikipedia.org Young mooneyes tend to feed in more benthic regions, eating immature caddisflies, mayflies, midges, corixids, and plecopterans.
en.wikipedia.org Consequently, dragonflies, mayflies, caddisflies and other water-seeking species actually prefer to mate, settle, swarm and oviposit upon these surfaces than available water bodies.
