Help please! I've noticed for the last 3-4 wks hundreds if not thousands of these little flying bugs buzzing in and out hundreds little holes (the size of the tip of a pencil) in the bare ground on my veg garden plot (haven't planted anything yet). They are very little, 2 slim wings, resemble like a cross between a tiny bee with a flying ant, they are not aggressive but when touched they emit a buzzing vibration, they are not furry, their butts and legs have yellowish stripes on them...6 legs and 2 slim wings, what are they? can I still plant produce in this plot? any help will be happily appreciated!
