What’s that? What is making those piles of tunnels in the dirt hills along the trails? Miner bees!
Miner bees look like bumble bees. They are fuzzy and yellow on the top half of their back, and black on the bottom half.
Miner bees are ground nesting bees. Each one of those tunnels is a nest. They are said to be friendly bees. They are not aggressive and do not sting or bite.
You can find several miner bee nests on the Shiloh Greenway between Church Street Park and the big hill along the Hamlet in the Park neighborhood.
