Janet writes to GMG the following, “Can anyone identify this moth/butterfy that was hanging in East Gloucester today?”
The Question Mark Butterfly (Polygonia interrogationis), so named because when the wings are folded, you can see a little raised backward question mark pattern, in white, on the underside of the hindwing. They feed on floral nectar, but are often seen on trees because they also feed on sap. And they alight on people too, because they are attracted to the salts and minerals in human perspiration. Both last year and this year we have had a tremendous influx of Question Mark Butterflies.
I can’t at the moment locate a clear photo of the underside, but know I have video footage (somewhere) that shows the question mark pattern and will try to find this weekend.
