Hyposoter placidus is one of the two common parasitoids hosted by the Small Copper butterfly (Lycaena phlaeas). This male emerged from a caterpillar found in early May on Baildon Bank, VC64.
The caterpillar, which had been feeding on potted Sheep's sorrel, sought out a sheltered place underneath the pot where it became mummified before it could pupate.
The adult Ichneumon emerged on 9th June 2013.
