July is summer in Carl Schurz Park

We are really looking forward to the possibility of a soaking rain, as we have had a drought for the last couple of weeks, with hot temperatures and strong winds adding to the drying effect.

Nonetheless, all the flying insects of summer are hatching out, and dazzling us with their beauty and pollinating abilities. There are numerous different species of bees, from extremely tiny to quite big bumble bees, and several large spectacular wasps too. The solitary wasps, like the magnificent Eastern Cicada-killer Wasp, hardly ever sting, and don't represent a threat to humans, despite their awe-inspiring appearance.

Insect and mite plant pests in NYC

NOTE: this is currently an early draft and therefore incomplete!

I decided to start putting together a journal post about the plant-pest species of arthropod that I have observed in NYC. These are mostly insects, but also mites. It will take me a long time to compile the list, as there is no project that covers this. Also the list could potentially become so long as to be unmanageable!

The list will NOT include all the various leafminer species I have found (leaf miner flies, moths, beetles, etc) -- those I have already listed in a separate journal post. However, on the rare occasions when I have managed to photograph the adult of a leafminer insect, that will be included here. The list will also NOT include the numerous gall-making creatures, as I intend to make a separate post about them.
