Window Gnat
A small, delicate fly with dark-spotted wings often found resting on windows and walls. Larvae develop in fermenting organic matter and tree sap runs.
Did You Know?
Despite being one of the most commonly encountered flies on windows throughout Europe, this species remains largely unstudied and overlooked by entomologists.
Bolas Spider Moth Mimic
An Australian moth whose eggs are so tough they resemble seeds and can survive passage through a bird digestive tract — potentially allowing bird-mediated dispersal over long distances.
