The Lady Bird Johnson Wildflower Center Fauna Project |
A team of five completed this week's survey; conditions were sunny and cold. The Dainty Sulphur is a species that is active year-round in our area. During the summer, adults are light yellow, but those that mature in the colder months are much darker, as shown below. When the insect is immobile due to low temperatures, the green/gray scales act as camouflage.
