Behavior and Characteristics
It feeds on plant matter and small aquatic insects.
The summer fishfly undergoes complete metamorphosis.
1. Egg Stage
Large masses of 200-3000 eggs are laid near still water bodies.
2. Larva Stage
After hatching, the larvae crawl to the nearest source of water live on detritus, or become omnivorous. This is the longest stage of their life cycle, lasting 2-3 years that is spent underwater. Once large enough, the larvae leave the water and pupate near or under bark.
2. Pupa Stage
This stage lasts a couple of weeks.
3. Adult Stage
The adults emerge and live for just a few days, in which they lay eggs.
