The past week I noticed swarms of flying insects around my house and on my trees at sunset. I initially thought those are some kind of bees or wasps, but since i don't see them are day time, I didn't pay too much attention.
I happened to be outside at sunset today and caught the sight of some of them flying close by. I realized these are not bees or wasps. I have not a clue what they are and it looks like they are flying everywhere and mating.
I am starting to worry if these bugs will harm my garden especially the fruit trees it is mating on.
What are these, if I need to get rid of them, what can I do without using pesticides?
