Question: It’s fall, why are all these bugs coming into my home? I’ve never seen them before!
At this time of year, this is one of the most common insects that you might run into. They are relatively new to our fauna since they were not found in Ontario until about 1985. The Western Conifer Seed Bug or Leaf footed bug (Leptoglossus occidentalis, family Coreidae) is native to the West coast of North America and has slowly moved east (into Europe as well). It is adapted to a little milder climate and doesn’t really like Ontario winters (me either!). So what does it do in the fall? It looks for a nice, warm place to overwinter; sounds like your house is perfect! Most of the time they will go below the leaf litter on the forest floor or some other sheltered area but heated buildings suit them just fine.
This true bug (order Hemiptera) looks very similar to assassin bugs (which I will cover at a later date) but is easily recognizable by the zigzag white line across the wings and the alternating white and dark pattern on the sides of the abdomen.
