Although it may seem like there are bugs everywhere, their populations are actually in trouble. In 2016-2017, 51 species of butterflies, 111 species of moths, and 3 species of bumble bees in PA considered to be at risk. USFWS has listed the rusty patched bumble bee as endangered and is currently evaluating American bumble bee, Monarch Butterfly, Regal Fritillary, and Frosted Elfin Butterfly for the endangered species list. Additionally, a lot of the bugs that are present in excess are invasive species and are out competing with the native bugs that we need to pollinate our agriculture and protect our ecosystems.
