Thanks John! That looks like it.
Made for piercing and sucking with a painful bite.

For reasons that have never been adequately explained, many thrips will bite when they land on human skin- even the vegetarian ones. Bites that develop within homes are usually the result of vegetation near an air-conditioning intake vent or other active intake of air from the outside that throws these creatures into the house. It is possible that a plant within the home could be the source of the thrips, but for some reason I’ve only heard of thrips being sucked in from the outside.

Luckily they were outside throwing the baseball when this attack happened. It is reassuring to know they aren't natively found inside. Thanks!
