Great Golden Digger Wasp

A large solitary wasp with a golden-furred thorax and orange-red legs that digs burrows in sandy soil. It provisions its nest with paralyzed katydids and crickets.

💡

Pitted Resin Bee

A small, stout bee with bold yellow and black markings that constructs free-standing resin nests on rocks and walls. It is widespread across Europe.

💡

Did You Know?

Unlike most bees, it builds its nest cells as exposed resin lumps on open rock surfaces rather than hiding them in cavities.
