Hi, Can you help me ID this beautiful bug that’s been sitting on my garage door opener in Massachusetts. It is most similar in appearance to the
Marmorated Stink Bug, Halyomorpha halys Stål. However, the triangle
markings on its wings are very exotic and remind me of the Giant
The underwings have 4 white bands
The back legs have 3 white bands
the antenna have 3 sections of increasingly lighter browns
The brown eyes extend outward from the head and are set on either side
of an elongated head
It has a white leaf/spade pattern painted on the the second section of
its body attached to the head.
The second part of triangle on its wings/back have outlined white
rectangles set at a 45-degree angle from the center line of the wing.
The Western Conifer Seed Bug, Leptoglossus occidentalis, is native to the Pacific Northwest, but sometime in the 1960s, it began to expand its range. We suspect the range expansion is connected to the increased frequency of human travel patterns. Western Conifer Seed Bugs often attract attention when they enter homes to hibernate as the weather begins to cool.
