What is corydalinae?

Corydalinae is a subfamily of the family Corydalidae, commonly known as the dobsonflies or fishflies. They are a group of large, aquatic insects that are found in freshwater habitats across the world. The subfamily includes around 450 species that are known for their distinctive mandibles, which are used by males to impress females during courtship.

The dobsonfly larvae are aquatic and can be found in small streams and rivers. They have long, mandibulate jaws that are used to capture and eat other small aquatic animals. The larvae also have gills that enable them to breathe underwater.

The adult dobsonflies are typically nocturnal and are attracted to light sources. The males have large, impressive mandibles that they use to attract females and intimidate other males. The females are larger than the males and do not have such exaggerated mandibles. They lay their eggs on rocks or vegetation near the water's edge.

Although dobsonflies have a fearsome appearance, they are harmless to humans. However, their larvae can be used as bait for fishing and are considered a delicacy in some cultures. The subfamily Corydalinae includes several species that are popular with fly fishers and are often used as models for artificial flies.
