Subarctic Crane Fly
A medium-sized crane fly with distinctive patterned wings and long, slender legs. Larvae develop in wet peatland soils. Adults are poor fliers and often rest on low vegetation in sheltered spots.
Did You Know?
The larvae of this crane fly can survive in waterlogged, low-oxygen peat soil by breathing through specialized anal papillae.
Hawaiian Picture-wing Fly (Silvestris)
A Hawaiian picture-wing fly closely related to D. heteroneura but with a normally shaped head. It is found in wet forests on Hawaii Island. This species and D. heteroneura are a classic study system for understanding speciation in progress.
Did You Know?
D. silvestris and D. heteroneura can hybridize in the lab, providing key insights into how new species form through sexual selection.
