'Horned Devil' Near Mount Vernon

RIVER FARM DRIVE, Sept. 1. A man found an unusual looking caterpillar at the base of a tree at a home near Mount Vernon Estate and Gardens. Concerned that the large green bug was vulnerable to predators, he boxed it and drove it to Mount Vernon, seeking advice. Unable to obtain information there, he took it to the Alexandria animal shelter. The caterpillar, which measured more than five inches long, was identified as a hickory horned devil, with characteristic orange-and-black spikes protruding from its segments.

The man took a picture of the caterpillar with his digital camera before leaving it with animal control, which transferred it to a nature center. It is expected to grow into a royal walnut moth, with a wing span of five to six inches.

Ill Owner's Parrots Aided

ALLISON ST., 500 block, Sept. 1. Animal control was asked to help paramedics with two large parrots in a house where their owner, an elderly woman, was found unconscious.

Man Feeds Baby Squirrel at Work

ARLINGTON AREA, Sept. 7. An orphaned baby squirrel found in a back yard was surrendered to animal control. A man had kept the newborn for four days, taking it to work so he could regularly feed it infant formula. Animal control sent the squirrel to a wildlife rehabilitator.

"Although some people try to help wildlife by feeding it, the public should not dispense infant formula or other food, which could be unhealthy for the animal," said Kay Speerstra, interim executive director of the Animal Welfare League. Speerstra said that the public should call animal control immediately after finding a wild animal in need and not to handle it or keep it as a pet.
