Early blister beetle - Apalus bimaculatus
Maybe these beetles are the very first spring bugs with their early swarming in the beginning of February here in Hungary. On warm sunny days with a 10°C degrees temperature males fly above the ground looking for sitting and running females. They belong to the family of blister beetles (Meloidae). Larvae are feeding mining bee larvae.
The photo above shows a male. It's a single shot taken with 100mm macro lens on a 36mm extension tube. Natural light, tripod and cable release were used.
On the picture below a female sitting quietly on a twig.
