First pic is a female ovipositing in the bark fissures of a crabapple tree. Second pic is of a male on the hunt for females. A number of males were swarming over an area of a northern red oak where evidently a female had been recently. They also swarmed to my hand as I had just picked up a female and had pheromone on my hand. Notice the sexual difference in the antennal structure and the elytral color.
