Orange Dog

Dear alf,
Thanks so much for providing documentation of Orange Dogs in your New Hampshire garden seven years after first seeing an adult Giant Swallowtail, a species reported in Vermont on BugGuide, but not in New Hampshire.  According to the Missouri Botanical Garden site, Gas Plant is in the citrus family Rutacea, which is consistent with BugGuide information on larval food plants.

Variegated Fritillary Caterpillar

Dear Sharon,
We believe this is a Variegated Fritillary Caterpillar and according to BugGuide:  “Larvae feed on Violets & Pansy (
Viola), Flax (Linum), Passion Vine (Passiflora), Damiana (Turnera), Moonseed (Menispermum), Mayapple (Podophyllum), Stonecrop (Sedum), Purslane (Portulaca) and others. Adults are fond of flowers, and especially seem to like Thistles and yellow Composites. They also frequently visit damp ground.”
