Brown Prionid ~ Orthosoma brunneum

This Brown Prionid is a male. The almost combed antennae are an indicator of the gender. The toothed edges of the thorax is a species indicator. The Brown Prionid was once a food item. Probably similar to shrimp or lobster. Yummm. The Brown Prionid is about 1.5 inches long. They can make a pretty loud thump on a window. This is a boring beetle but not in the not so interesting sort of way. They eat dead wood, so they are just out there making compost until they go for a flight. The Brown Prionid can be a spectacularly large surprise when they arrive at your window.
