Mellinus arvensis: the field digger wasp

Post date: Sunday, 20 November, 2016 - 21:32

Everyone is surely familar with the common yellow and black wasp species, Vespula vulgaris; a social wasp, living in colonies and extremely aggressive if disturbed or threatened. However, there are many other species of wasps, not all of which are yellow and black, and most of which live a pretty solitary life. This species, Mellinus arvensis, is one of those solitary wasp species.

Also known as the field digger wasp, this species excavates a burrow by digging with her mandible and legs. She then finds a spider (or may be more than one depending on the size of the spider) and paralyses it with her sting and then drags the spider in to her burrow where she then lays her eggs inside the spider. The eggs hatch and the larva eat the spider before pupating and over wintering to the emerge as adults in the spring.

A bit gruesome may be but this sort of thing is going on, usually unseen, in the natural world all the time.
