3 Shakes of Pepper..........

I've caught a few Peppered Moths recently, but they seem to have just about finished for this year. I have been lucky enough to trap all 3 sub species too!

Biston betularia
This is the commonest of the 3 and the most regular in my traps.

 f. insularia
In between the 2, I have only trapped 1 of this form on 28th June.

 f. carbonaria
Only 1 trapped, but striking. This form is now in decline due to less air pollution! Apparently in the London area 100 years ago, this form was once the commonest. The moth over it's many generations since has gradually favoured the now most abundant white form.....
