|Leaf footed bug - REK|
The leaf footed bugs are in the the family Coreidae which feed on plants. They have a drill like mouth that is used to inject digestive enzymes into the plant before they suck out the externally digested meal. The enzymes digest cell walls, liquifying its content and can break down some plant toxins. This allows the bug to feed on plants which other species cannot use. Leaf footed bugs can give off a bad odor if disturbed.
The leaf shaped hind leg is especially prominent on the species I found. Its distinctive color pattern led to an identification as a Leptoglossus species. When they fly they make a faint buzzing sound and their legs hang down like a wasp, a fake warning to man and beast. They are harmless to humans, commonly found feeding on yucca and other related plants.

I have been following these L. clypealis on our yucca for a number of years and they never seem to do any significant harm. On the other hand there are a lot of them around so freezing one probably hasn't upset the balance of nature.
