Lepidoptera

Beetles, hard forewing, hydro or aeroneustic depends on sp., shred and filter. larvae have no compound eyes, just eye spots. adults and immature share same environment.

Coleoptera

Fly, bi winged, hydro or aeroneustic depends on sp., some filter feed.

Diptera

Flowing water: streams, rivers

Lotic

Pooling water: pools, ponds, lakes

Lentic

food sources within the water. Algae, diatoms, cyanobacteria, plant planktonic

Autochtonous

Food sources from outside the water. Plants, falling leaves, etc. Donated material.

Allochtonous

Sp. live in same place as a juvenile and adult. Dont look much different from each other.

paurometabolus

diatoms, algae, cyanobacteria, bacteria, fungi. mix of auto and hetero trophic microbes. slippery stuff on rocks.

Awfwuchs

1 generation per year

univoltine

more than one generation per year

multivoltine

takes 2 or more years per generation

semivoltine

slow growth over the year after emergence

slow seasonal

diapausing eggs, no growth over many months. grow to full size in a short time period. decrease risk of experiencing/dying from dry spells as larvae.

fast seasonal

overlapping age classes all year. reproduction and pupating occurs all year. increased success rate in the case of a random event (dry spell, flooding) that may impact one or more age classes.

non-seasonal
