Goliathus posted a topic in Beetle PhotosShort video of a Bumelia longhorn (Plinthocoelium suaveolens), found today. Both sexes are iridescent metallic green, with red and black legs. Males (like this one) have extremely long antennae. Although their host tree is common in my area, I've only ever found a few of these beetles (possibly, because they only tend to emerge once the heat and humidity are so stifling that wandering around looking for them is very rough going! It's a much-sought species by cerambycid collectors, and I didn't even know they existed in my area until I intentionally starting looking for them around 5 years ago. I've heard that they'll definitely come to bait traps, but I've only ever had any real success finding them sitting on the trunks of their host tree (Sideroxylon lanuginosum). Like many other longhorns however, they will come to sap flows on some other tree species, such as Red Oak (Quercus buckleyi).
A short video of a pair of Plinthocoelium suaveolens, a bright metallic green longhorn beetle that starts emerging around late May / early June, that I found on a gum bumelia (Sideroxylon lanuginosum) tree in my backyard. The male is the one with extremely long antennae. As you can hear in the video, this species, like many longhorns, has the ability to make a "squeak" through stridulation. Gum bumelia seems to be the only host plant of Plinthocoelium in my area (the larvae live in the roots), though I've read that they are also sometimes attracted to Tupelo and Mulberry.
