この巣箱は隙間から小さいオオスズメバチに侵入されてしまいましたが、このオオスズメバチは大きい個体だったので侵入できずに木を噛り穴を開けようとしています。このまま大きい穴を開けられては困るので捕獲してついでに観察しました。粘着シートの粘着が弱くてビクビクしながら撮影しました。毒針で攻撃するところが観察できます。今年は多いですね・・・もう来ないで・・・
This nest box was invaded by a small wasp through a small opening, but this wasp was a large one, so it was unable to get in and was trying to make a hole by chewing on the wood. I captured it and observed it because I did not want it to make a big hole. The adhesive sheet was not sticky enough, so I was scared to take pictures. You can see it attacking with its poisonous stingers.There are so many of them this year... Please don't come here anymore...
