Spotted Sedges

Interesting facts

Adults often emerge in huge swarms, making riversides look alive!

Scientists study their presence to check how clean our rivers are!

Some types of these insects don't even eat once they become adults!

Their underwater larvae are like tiny architects, building silken homes!

Special abilities

Spotted Sedges can weave intricate silk nets underwater because this helps them trap tiny food particles flowing past.

Spotted Sedges has mottled, spotted wings that help them blend perfectly into their tree bark or rock surroundings, avoiding predators.

Spotted Sedges larvae can only live in clean, moving water, which helps scientists measure how healthy a river is.

Diet & Feeding

Larvae filter tiny bits of food from water; adults eat little to nothing, focusing on reproduction.

Age differences: Larvae filter-feed on microscopic particles, but adults often do not feed at all.
