I think that's a crane fly. Adults are harmless; larvae feed on decaying plant matter and sometimes roots. Birds and lizards like to eat 'em.I didn’t notice till just now but in the 2nd picture top left corner there’s what looks like a giant mosquito.
Yes, wonderful that you noticed them. I planted seeds around the entire edge of the bed only 10 days ago. My husband got me the soil from someone who got it from someone who grows mushrooms. Well it must be really good type of soil because my tomatoes, zucchini and marigolds are just taking off.Are those marigolds you have popping up?
