The insect had a brownish colored abdomen with a pattern on it and long front antennas. I had never seen an insect like it before. I was intrigued enough to run back inside the office to grab my camera. After taking a photo of the bug, I Googled “large brown bug with antennae” to see what I could find out about it. I figured out that the mystery bug was a Western Conifer Seed Bug. Western . . . immediately I thought I had made a mistake identifying the insect. Since I live on the east coast, I checked to see if perhaps there was an eastern variety of seed bug. After a little reading on the Penn State Entomology web page, I learned that the western conifer seed bug has been expanding its range into the east. At first it was identified in Pennsylvania and now the bug ranges in New Jersey and even into Canada.
Although the western conifer seed bug I saw on the sidewalk was barely moving, apparently they buzz and fly like a bee. The bad news for me is that the bug is considered a pest that likes to come indoors, inside homes and office buildings, in the winter. Perhaps this western conifer seed bug has been hanging around with the stink bugs at my office all winter and I hadn’t noticed it before.
