A recent study shows that the populations of beetles are dwindling, and this could end up being just as problematic as the problems of bees and butterflies

The research, published in the Journal of Applied Ecology, found that 3/4 of the beetle species examined had declined in number over the last 15 years. The abundance of half of these species had fallen at a rate equivalent to 30% per decade. Scientists warn that these declines, comparable to those seen in butterflies and moths over the same period, are of serious conservation concern. The study focused on ground beetles or 'carabids'. Many of these species perform valuable tasks in their ecosystems that we'd miss if they disappeared.
