What is the role of aquatic flies in sewage treatment?
Prevent surface film of ooze.
bottom dwellers - on or around substrate
How does AE interact with the food web?
Terestrial + aquatic organisms heavily forage on both aquatic + terr. stages of aquatics.
Water beatles + bugs
What are some car related problems that come with aquatic insects?
They could get stuck or lay eggs in car finishes
burrow in soft-bottom substrates
Bottom-dwelling insects maintain a relatively ____1____ position in the aquatic environment
1.) stable
Reside in plant stem root systems; moss
What is the role of bacteria in sewage treatment?
promotes breakdown of sewage
benthic insects that cling to substrates

What is a bioassy?
Biological indicators used soley for the purpose of targeting toxins in streams, etc
Wing pad
Developing or sheath of developing wing
How does AE interact with other disciplines?
Many aquatic flies are of importance as disease vectors. AE interacts with medical entomology + parsitology.

Water flows continually throughout year
What is the difference b/w growth and maturation?
Growth - increase in size
Maturation - morphological + psychological growth
