The Twin-spotted Quaker is a species which is variable in colour, from pale buff to reddish brown. You can easily tell it apart with the twin black spots on the fore wing. They may be missing on some specimens where they only appear as rufous marks. The Twin-spotted Quaker is attracted to light and sugar. It over winters as a pupa, inside a cocoon, in the soil. |
