Megacyllene robiniae (Locust Borer)

I’ve already posted the picture of the variegated fritillary (Euptoieta claudia) taken at the demonstration garden at the county‚Äôs agricultural farm park. This picture won’t be so popular, because everyone loves butterflies, but I thought it was a pretty enough beetle to deserve a shot at fame. Actually, the locust borer (Megacyllene robiniae) is a pretty significant pest. The larvae live in and eat the wood from black locust trees. The adults eat pollen, particularly from goldenrod (Solidago species). This one is worn. The yellow bands that usually go all the way across the back of the thorax have been rubbed off in the middle. Most of the yellow on the abdomen is gone, as well. Still, it’s a handsome and distinctive horned beetle.
