CLUSTER FLIES have been out in numbers for the past few days, maybe about a week. Is it mating time? Also saw a sparrow in the shrub outside the kitchen window a few days ago. It didn’t stay long enough for me to identify it. A species of wasp that seems to have been hibernating in my house is beginning to reactivate. I’ve found two dead bodies and noticed one live wasp upstairs. Maybe POLISTES WASPS?
