Surrey365; Day 107. The Anthrax Window Fly.
Ok, that might not actually be its name. It’s actually called the Mottled Bee Fly, but its Latin name is the slightly alarming-sounding Thyridanthrax fenestratus, so I like my name more. 😉 It’s a wasp fly, rather than a bee fly, in fact; it’s a parasitoid of the sand wasp Ammophila pubescens. The bee fly lays its eggs in the larva of the sand wasp, or in the prey caterpillars collected for it, and on hatching, the larva eats its host.
Ah, the wonder of nature. 😀
It’s rare and endangered, only occurring in a few lowland heath sites, and surprisingly appealing for a fly (probably my least favourite creatures, frankly).
