Green Tortoise Beetle
A broadly oval, flattened beetle that is bright green in life, with transparent margins around the pronotum and elytra. It closely resembles a tiny green shield when viewed from above.
Did You Know?
The green coloring fades rapidly after death, turning dull brown in preserved specimens, which is why museum collections do not reflect its living beauty.
Woodland Pterostichus
A medium-sized, shiny black ground beetle with distinctive oblong punctures in rows on its elytra. It is one of the most characteristic carabid species of European deciduous forests.
Did You Know?
It is used as a bioindicator species for ancient woodland health; its presence is associated with undisturbed forest with deep leaf litter.
