オサンポ walk - 植物plant: 虫食い落ち葉 a fallen leaf that was bitten by an insect

虫食いの

落ち葉枯れ葉や

師走なり

Fallen leaves had small holes

Because of insects bites

It’s December 

虫食い穴だと思っていますが、万が一違ったりするんでしょうか？？

When I see some small holes on leaves, I guess that any insects do this. Am I right??

*I’m not sure if my English grammars are correct.
