Sand Wasp

A robust wasp that digs burrows in sandy soil and provisions them with flies. It progressively feeds its larvae fresh prey over several days.

Dotted Bee Fly

A spring-flying bee fly distinguished from its commoner relative by spotted wings and a darker fur coat. Its larvae parasitize mining bee larvae of the genus Andrena.

💡

Did You Know?

It appears only in spring for a few weeks, closely tracking the flight season of its specific Andrena bee hosts.
