Currently I have 8 dendrobiums in spike or bloom. As I was watering them yesterday I noticed a few specimens with random buds either damaged or missing. A thorough check for pests turned up nothing. While fertilizing today I noticed even more missing buds. As I was feeding the last of the dendrobiums I found this florescent green guy crawling on the surface of the lava potting medium. I spritzed him with a little Raid Max after taking his photos and he won't be munching on my chids any more.
This scarab beetle is a Cotinis notida, commonly known as the Green June Bug. Their grubs eat grass roots, decaying material and dung. The adults eat a variety of fruit and vegetation. His appetite for dendrobium buds led to his demise.
