Australian Scorpionfly

An Australian hangingfly that suspends itself from vegetation and catches prey with its raptorial hind legs. Males present captured prey to females as nuptial gifts.

💡

Did You Know?

Female Australian scorpionflies assess nuptial gifts by tasting the prey — if it is nutritionally poor, they reject the male and fly away.

Arctic Aphid

A small, pale green aphid that is one of the most northerly herbivorous insects on Earth. It feeds on the sap of Dryas octopetala and other Arctic plants. Populations are entirely parthenogenetic in the High Arctic.
