The Mrs.

This is the third female stag beetle I've found in the garden this week (different sizes). She spends 6 or 7 years underground and then comes above ground for a couple of months to mate.
Her final act before she dies is to make her way back to the place from which she emerged where she buries herself into the ground about 12" down and lays her eggs.
I just saw a male 'flying' around tonight ...
