Where to look

Old rodent burrows and wall cavities; the huge bees flying low in February are queens.

Worth knowing

Only the mated queen survives winter; the entire colony β€” workers, males, the old queen β€” dies each autumn. So a nest is a one-year object, and the low, searching flight in early spring is a queen looking for a hole, not for flowers.
