MSU Extension Entomologist Laurie Kerzicnik identified the tiny biting insects as “winged thrips” instead of biting midges aka “no-see-ums”, which explains why they are present in hot, dry conditions, stated Powder River Extension Agent Mary Rumph.

The bad news is that, according the Kerzicnik, both adult (winged) and immature thrips can bite people. They use their stylets (part of their mouthparts) to pierce skin and extract fluids. They are likely going after moisture in human skin. She explained the attacks usually occur in hot, dry weather. They are plant pests on numerous crops and are likely migrating to another host. The bite reactions range from slight itching with red marks to sharp, painful bites with welts and swelling. They do not transmit any diseases.

On a more encouraging note, Kerzicnik said, “They are migrating and will be gone soon. When cooler weather hits, they will likely dissipate.”
