Bee flies such as this one gather sand into a chamber at the end of the abdomen - sand which will then coat their sticky, thin-shelled eggs. This sandy coating protects and probably camouflages the eggs when they are dropped onto the sand.

Comptosia sp.

Yet another bee fly. A huge one! And yet another species we’ve not seen before.

Ligyra are known parasitoids of ground-nesting wasps … so the nearby sand wasp larvae are probably among their local hosts.

Ligyra sp.

Very like a species we get at home. And yet another parasite of ground-nesting bees and wasps.

Meomyia sp.
