Three-punctured Ground Beetle
A common medium-sized metallic green or bronze ground beetle with distinctive punctures on its elytra. It is abundant in agricultural fields across Europe and important for weed seed consumption.
Did You Know?
It has been observed carrying seeds back to its burrow to eat, behavior more commonly associated with ants than beetles, and may help disperse some plant species.
Wide-Horned Scarab
A small, yellow-brown tunneling dung beetle with dark markings on the pronotum. Males have two short broad horns. It is one of the most successful introduced dung beetles in Australia and the Americas.
