My backyard has been completely over run by thousands of these bugs over last 6 months. What are they?
This is a Red Shouldered Bug, Jadera haematoloma, and according to BugGuide, the habitat is: “Yards, gardens, riparian areas, and other areas in association with hostplants. Often found in large aggregations feeding on leaking tree sap, dead insects, or seeds that have fallen from trees overhead. Also forms aggregations in winter to hibernate, often in association with human residences.” BugGuide has a list of host plants, and eliminating the food source should help to control the numbers of Red Shouldered Bugs in your yard.
