if you are in GB then yes this is
major, a female whereas the other photo is male. size means little with these parasitoides and colour and furryness is often a function of age/ware.

Do the adults overwinter ?
Brian V.
no, they overwinter in their host burrow, either as full fed larvae or pupae, if former then pupating in late winter, in the case of major and discolor emerging March April (males usually first) leaving their pupal exuvia sticking out of the soil.
