This wasp flies particularly late in the season, and is common in autumn - although occasionally it can be seen much earlier, as in the top photograph. In autumn, Mellinus arvensis a regular visitor of flowering Ivy, Hedera helix. Ivy is one of the last nectar sources in the season, and attracts scores of flies, wasps, bees and butterflies - a flowering bush of Ivy can not only be smelled, but even heared from quite a distance, because of the humming flies, bees etc! The wasp Mellinus is not after the nectar, though: it hunts for flies. Since potential prey is abundant, you can often see hunting wasps crawling through leaves and flowers, and occasionally you can witness an attack and the handling of prey, as shown here.

Female wasp inflicting a paralyzing sting to her prey, a fly in the genus Pollenia. Next, female handling its Pollenia prey. Normally the wasp gets its prey quickly under control, taking it in her legs under her belly, and flies of. Somtimes, however, it seems to be hard to find the ideal position, and the wasp struggles with its paralyzed prey to find the proper position before flying off.
