Two millimeters long, under the microscope at 40x and 20x. Found the first on a curtain two weekends ago. Last Wednesday, when it got up to about 70F, there were a bunch of the window screen. And, being 2mm long, inside the screen. This is a psyllid, one of the creatures that induces galls in Common Hackberry. There are two hackberries down below, reaching up to about a story below us. This is the adult form that emerges from the gall.
Now, these insects are awfully small, but I don’t see why a Ruby-crowned Kinglet wouldn’t eat them. I mean, it would take a lot to fill up even a RCK, but it looks like there are a lot. And kinglets have kept popping into these trees recently…
