  1. This is pure awesomeness. Posted 11 months ago
    1. Thanks Ferdy, it's one of my hobbies to try and find out how to ID eggs and early development stages. The insets showing the aeromicropilar processes (the little "tubes" around the "lid" of the egg) go to documenting characters that may be used for this purpose :o) Posted 11 months ago, modified 11 months ago

''Picromerus bidens'' is a carnivorous species of shield bug in the family Pentatomidae. A large and distinctive predatory shieldbug, which has unmistakable thorn-like projections on the front of the pronotum.

It has a wide distribution in the Palaearctic, from 64°N to North Africa and from the British Isles to China. It has also been introduced, probably more than once, to North America, where it has been recorded from more than 180 sites .
