Skywatch Friday: Gypsy Sky



A Gypsy Moth Caterpillar hangs from a branch by a silk thread

While the caterpillars are still small, their fastest mode of travel is to hang from a branch suspended by a fine silk thread and wait for the wind to carry it away.


My previous post garnered some very nice comments and raised some very good questions.

Jack and Joann asked if we have Japanese beetles. Yes, they do create a problem with ornamentals and grapes but no significant damage is done to other indigenous species.

Abe raised the question as to whether man had something to do with the problem. Yes, the Gypsy Moth is an alien invasive species brought to the east coast by a profit seeking businessman in the 1800’s. The only profit to be made from them is by those involved in making, distributing, and spraying pesticides. Since they have no significant natural enemies outbreaks are extremely damaging, particularly to our native oaks.

Fishing Guy mentioned that he hopes the spray doesn’t hurt the birds. The insecticide of choice is Bacillus thuringiensis or BT for short. BT is a bacterium that is fatal to caterpillars. No effect has been documented on any bird, fish, or animal species.

  1. Thanks for the explanation about this pest. I had some inkling that it was man who made the problem and the rest of us will have to clean it up. It is almost always this way. Nature, left alone, pretty much takes care of itself and does a fine job.

    I am glad to see the beast against a blue sky.
