Thank you for this great site!
Recently, I found piles, and individuals, of these red and black bugs on a trail around the Volo Bog (IL).
They were most often seen en masse on bird/animal droppings.
Though we have no dearth of new postings of Eastern Boxelder Bugs on our website at the moment, we are fascinated by your report that you found them feeding on bird and animal droppings. They were most likely extracting fluids since they have mouths designed for sucking. Your photograph includes a seed that appears to be a maple “helicopter” and that would indicate that the typical food of the Eastern Boxelder Bug is present in Volo Bog.
