There are 19 genera and 55 UK species in the family Limnephilidae. It is a very large and complex family.
The adults are usually brown in colour, often with narrow mottled or patterned forewings and much broader, transparent hindwings. The aquatic larvae construct portable cases from a wide variety of plant and mineral materials
Note: Not all species of caddisfly can be identified via an image in itself, and requires closer scrutiny with a microscope. This is either Stenophylax sp. or Micropterna sp. as indicated by an expert at iRecord.
