Description:

Looking in my 2005 Collins guide to British Insects, this species is described as being active in the adult form May-August. Yet here in sunny Dorset it seems to get earlier every year. I've seen it in April in the past few years but 2011 is my first March sighting! Saw a few so it wasn't just one freak emergence - and as you can see from the photos this one was living up to its reputation as a voracious predator.

Green Tiger Beetle

I have often seen them in March on the Bournemouth cliffs, and in one year even in late February. In some years I have seen a few in the autumn after a long gap without any. I am unclear as to the phenology of this species.

Over-wintering

Interesting observations. It does seem that some over-winter. If you catch the early ones you see and check their jaws, you should find that they are a bit worn and blunted, unlike the needle-sharp jaws of a freshly-emerged adult.
