Don't know what they are,no one here does, but the boats in the marina are awash in them. I've never seen them around the bay in the seventy plus years that I've been here. They don't seem to be interested in flying about or biting, they just get out of the breeze and poop. That's right POOP. Little black star shaped poops about the size of poppy seeds and they don't wash away. The proprietors reaction to the poops is "oh great and we're detailing boats now". At first sight one would suspect mosquitoes but though they have the appearance of mosquitoes they have no proboscis. Tried to research such things on the internet but with little success, every mosquito catalogued looked just like them, but not quite. They are approx. 5/8" and slender with wings. Any ideas?????
Some variation of the Mayfly. Google that and see if you get any clues. I wonder if the "poops" are actually eggs, since I don't think the adults eat anything. Omelettes, anyone?
I keep Silver Girl in Great Kills Harbor, Staten Island NY and one year we were invaded by hundreds of thousands of purple martins who regularly flew over the slips and hung around for nearly two weeks.

Hi Val,
I don't know if they can live in the cold north, but in Texas we have a critter called a "crane fly." They look like huge mosquitos, but they don't bite. In fact, down here many people jokingly refer to them as "Texas mosquitos." They get quite a bit bigger than 5/8", so I don't know if this is your bug or not ... here's a photo:
I'll take the mystery bugs over the purple martins any day. All the boats in my marina were covered with guano which was incredibly hard to remove, and it went on for about two weeks. For some reason purple martin poop is unbelievably hard to remove.
Fortunately the swarm of martins has only happened once in the nine years I've been at Great Kills.
NAW not a Texas mosquito too large( up here we call them out-house mosquitoes) and not a termite swarm. Termites have wasp like segmented bodies, but your suggestion that the black star poops might be eggs seems to be a definite possibility. The poops are gone and embryo like gelatinous sacks remain. They wash away easily.
On the bright side is that their numbers are greatly reduced possibly due to the arrival yesterday of a large flock of barn swallows.
I checked several marina's to the west of here and there were none to be seen.
