Description |
||
Masked hunter is a medium-sized assassin bug. It is native to Europe. It was accidentally introduced into North America and is now common in the eastern and central United States. It is common in Minnesota. Adults are ⅝″ to ⅞″ in length, elongated oval in shape, and entirely dark brown or black. The thorax is shiny and has two noticeable bumps. The thorax, abdomen, and legs are sparsely covered with straight, spreading hairs. The wings are leathery, extend the length body, and are held horizontally over the abdomen. When viewed from above, the edges of the abdomen extend laterally beyond the wings. The head is small and attached to the body with a distinct neck. There are both large compound eyes and small simple eyes (ocelli). The protruding mouth part (beak) has 3 segments. It is short and curved. When at rest it is tucked into a groove between the forelegs. The antennae have 4 segments, are slender, and are moderately long, much longer than the head. The third leg segment (femur) on the forelegs is thickened. Nymphs are similar in shape to adults but smaller. They are well camouflaged. They exude a sticky substance that causes bits of dist, lint, and other debris to stick to their body, antennae, and legs. |

About
Published on Jun 26, 2016 Masked Hunter (reduvius personatus) found in the house ( Fort Collins Colorado ). Black beetle with flat long back. Didn't fly but it looks like it has some wings. Ended up releasing him in the garden to help eat the little plant killers. |
