Species group · Insects
WAnimals has 2 species of sedge, spread across 2 families (Limnephilidae, Phryganeidae).
Ranges calculated from the profiles that record the figure, not from all 2.
Each one has its own full profile. This group does not replace them: it brings them together.
No species documented in this group is genuinely at risk according to the IUCN, with the data available today.
Recorded in 46 countries. The ones with the most species in the group:
Caddisflies are the only group of aquatic insects to have made silk a central part of their way of life, and that innovation explains why they are the most species-rich order of aquatic insects: some 14,500 described in 45 families.
