Trombidium breei
Trombidium breei is a species of red mite in the genus Trombidium in the family Trombidiidae. It is found in Europe. The larvae are parasites/hosts of certain butterflies, particularly meadow brown, gatekeeper, marbled white, common blue and small skipper. They attach themselves to the thorax or legs of the butterfly and transfer from host to host when the butterflies alight to nectar at flowers.
