Vespa affinis lesser banded hornet ツマグロスズメバチ 黄腰胡蜂 My friend said it was a Vespa affinis from Ambon Island, Indonesia. It took me a long time to figure out which subspecies it belonged to. I now think it is Vespa affinis moluccana, but I'm not sure #wasps pic.twitter.com/tSpo9GDRCf

Polistes chinensis 角马蜂/中华马蜂/二纹长脚蜂 フタモンアシナガバチ On the way out to pick up a package, I saw a worker of Polistes chinensis collecting wood. As one of the most common and docile paper wasps in China, they are generally not aggressive towards humans. #wasps pic.twitter.com/mrxv7YAZtQ
