What are these bugs coming out at night and why do they die so fast?

At night usually past 12PM, these bugs about 3-5 times the size of fruit flies come out of no where and start flying insanely, mostly gravitated towards my lamp. After a couple of minutes of this, I'll hear a plop and look at my desk to see them upside down as if they're struggling to survive or something, and then they die.

What are these bugs, why do I have them, and why are they dying so fast?

IANYI[nsectologist]. However, a tentative analysis tells me that they burn themselves on your lamp. The majority of flying insects gravitate towards lamps. The reflex seems to be 'where there's light, there's an escape'. Geez, even I would fly into a lamp if I was made buzzing about after 12PM.
I suppose we need a picture and a location to go any further on their usual daily rhythm and behavior pattern, though.

Escape doesn't enter into it. Nocturnal insects like moths have evolved to navigate by the moon, which is so far away that they can fly all night in one direction with the moon, say, on their right. If they try that with light bulbs, they will sprial in and hit them. They die because they blind themselves, burn themselves, or hit themselves on your lamp.

Thanks. I was wondering whether I was right here. The effect is the same, anyway, is what I meant.

June bugs? The activity you describe is pretty accurate for them, but they're a hell of a lot bigger than 3-5x a fruitfly.

I think the bugs the OP are referring to look like delicate black mosquitoes with feathery antennae. Some kind of fly, I guess- a thin-bodied, soft fly, with a narrow, straight body- not a big jucy bean-shaped body like most types of fly. Definitely NOT a moth (despite the fluffy antennae) or junebug (not crispy). My apartment is full of them, too, starting every April.

If pseudostrabismus is right, they're non-biting midges.

those are what they look like, thanks, why are they ending up in my house and coming out of nowhere?
