Ascalphids are diurnal, sun-loving insects. Their brightly coloured wings and a habit of basking in sun with their wings open can often lead them to be mistaken for butterflies or moths. When the sun disappears they rest in a more typical Neuropteran fashion with their wings closed over their body.

Ascalaphids do not occur in Britain, but there are several species that can be found in southern Europe.
