jadera bug

What is a jadera bug. Is it beneficial or not?

Wildlife Expert - Ken Burton

The Jadera Bug (Jadera haematoloma), also called the Soapberry Bug and Red-shouldered Bug, is a member of the scentless plant bug family (Rhopalidae), which also contains the boxelder bugs. It congregates in large numbers to feed on fallen seeds of trees in the Sapindaceae, especially goldenrain trees. It is native to the U.S. and an excellent example of how a species can adapt rapidly to changes in its environment. Within the last 50 years, this insect has evolved hereditary variation in the length of its beak to enable it to pierce the fruit walls and reach the seeds of various exotic plants.

All native species are beneficial in ecological terms. What that means is that they evolved within their native environments and are part of those environments' food webs and nutrient cycles. That doesn't necessarily mean that humans find them beneficial. It would be nice if what humans thought of other creatures didn't matter, but unfortunately we are powerful enough that it does. So, in human terms, Jadera Bugs may be numerous enough that they become a nuisance by getting into houses and staining clothing, but they pose no real threat to either people or exotic plants; however, they provide no real human benefit either other than being of interest. That ought to count for something, right?
