Hydrotaea diabolus, Dalgety Bay, Ross Plantation, 24/05/18

Hydrotaea diabolus,
Dalgety Bay, Ross Plantation
NT1683
24.v.2018
NOFI status - no Fife records
NBN status - 2 Scottish records

After finding a female a couple of days ago which was waiting to be identified, I ran into a male yesterday and what a fantastic fly it is! The overall impression is a glistening blue-black with a brightly flashing silver face when the light strikes it at the right angle. It has bizarrely long legs, especially the central ones, and the fore and hind legs bear weird and wonderful appendages. The central femur has a spectacular upturned hair on its apex.

The female - note pale haltere

Peg leg - cilia on tibia also noteworthy
