I've been seeing alot of different wasps lately, what's goin' on?

Question

I've seen things like a huge, extremely dark blue wasp (You'd think it was black if you were far away) with big orange antennae. I also saw one that looked like the Master of all bees, as it's body shared the appearance of one, with what appeared to be 4 or 6 antannae with white bulbs on the tips. Then there was a simple one with lime stripes, And today I just saw one with a freakin' gold face, and some gold on its wings. The rest was black.

I'm not trying to keep them away, I just wanna know why they've been showing up, and maybe get them identified.

Answer 1

Its possible the wasps you see have a nest nearby. Also, certain times of the year, some wasp species have a die-off, where all the wasps die off except for the queen. This makes wasps like Yellow Jackets very aggressive during the late Summer/ early Fall months.

Answer 2

I bet there is a wasps nest nearby. Or  IDK!
