If Laurence Llewelyn-Bowen was asked to design an aquatic insect, this is what he might come up with. The smoke-tinted wings of the alderfly are folded like a roof and supported by a tracery of veins, in the style of a Tiffany lamp. Despite these stylish wings they don’t venture far from the water’s edge.
The alderfly larva is a predator, using powerful pincer-like jaws to to prey on aquatic insects such as caddis and mayfly larvae.
