The Lady Bird Johnson Wildflower Center Fauna Project |
Conditions were cold and sunny as a team of four completed this week's survey. Although the temperature had risen by the time we finished, there was still a dearth of flying insects. Both butterfly and moth caterpillars pupate before becoming adults. Butterflies never make a silk cocoon around their pupa, which is called a chrysalis, but some moths do. The examples below show two very distinctive moth cocoons compared to a typical butterfly chrysalis.
