Atylotus rusticus ♂, Tabanidae, (ID-cred: T. Zeegers)
Size: 15 mm
This horse fly species was a nice new acquaintance for me last summer. Like in most horse flies, females of this species needs a nice "pint" of blood, preferably mammalian, before they are ready to reproduce. Males on the other hand, are strictly vegan, feeding on nectar and pollen.
Typically this means you'll only ever find female tabanids (or they find you rather). So I'm a bit surprised to only have come across males of this species so far.
Horse flies are extremely fast fliers – often referred to as the fastest among all flying insects. Looking at the body shape of this fly I can't help but noticing what appears to be an almost aerodynamically perfect adaptation!
