6342 They are all over my house, and are getting inside my house! What are they? From Fawcett Hill, NB
Number 6342 These are small winter stoneflies (Plecoptera: Capniidae); they are harmless and there is no need for control. Their nymphs are found beneath rocks and gravel on the bottom of streams and rivers where they feed on plant material there; the adults feed on blue-green algae. The adults most often are seen in late winter/very early spring.
