Species with which Pterostichus madidus interacts


Martincito's picture

Size: 14-18mm

Identification: This beetle is shiny and black with two different forms: one with rufous (brown) legs and one with black legs. The best feature to use for identification is the fact that the hind angles of the pronotum are rounded. It is also wingless and the elytra are fused together.

And the best news of all - it likes to eat slugs!

two species

The picture on the right shows two species - P. madidus and, I think, Harpalus rufipes (or whatever its scientific name is now)
