|A locust borer beetle, Megacyllene robiniae.|
They spend their larval stages on black locust trees. When they are not busy eating goldenrod pollen, the autumn adults can be found on locusts tree trunks, mating or looking for good places to lay eggs. The larvae hatch before winter and spend the cold months under the bark. When the weather warms, they'll burrow into the trunk and pupate. They emerge as adults in late summer and early fall and begin the cycle again.
|The adult eats goldenrod pollen. Note that the third yellow stripe on its back is shaped like a W.|
|One of the prettiest insects ever!|

|Head-on, the fly looks like it is wearing a tiny gas mask. As it walks, it moves its wings in a rowing motion.|
Picture-winged flies lay their eggs in rotten vegetation. The larvae spend a few weeks feeding there, then pupate for a few weeks, and then emerge as adults. When the weather cools, late season larvae crawl into the ground and become quiescent for the winter. They following spring, they wiggle upward, pupate, become adults, and start the cycle again.
I saw numerous picture-winged flies sunning themselves on benches in Brooklyn Bridge Park this summer (I'm assuming they were sunning, but maybe they were speed-dating). The next generation is surely sleeping under the grass now, not to be seen again until next spring .
