Description

Siphonoperla torrentium can reach a body length of about 5–7 mm (0.20–0.28 in) in males, of about 5–8 mm (0.20–0.31 in) in females, with a wingspan of about of 13.6–15.4 mm (0.54–0.61 in) in males and of 15–17.5 mm (0.59–0.69 in) in females.[7]

Biology

This species of stoneflies has one generation a year (univoltine). Larvae can reach a length of about 9 mm (0.35 in). They are yellowish to light brown in color and show clear bristles throughout. There are dark spots on the head and pronotum. The pronotum is transversely oval and has long bristles. Tracheal gills are not present. They can be found in streams and small rivers. They have a predatory diet, while adults feed on pollen.[8]
