Orange Sulphur, Colias eurytheme
<LEP29>
This bright butterfly, common in summer over much of North America,
has followed the spread of alfalfa.
Hence it is often known as the Alfalfa Butterfly. The picture shows a female upper side,
sunny orange with yellow-spotted black borders, black spot on forewing, and a
red one on the hindwing. The males’s
underside shows orange yellow with a row of brown dots and a silver spot. Drawing shows a pair on the flower of red
clover. |
