The body is yellowish white at first, but many reddish-brown spots appear on the back after the first molt. After the last molt, the caterpillar loses its spots and becomes solid green or copper. Pupae are usually found in a rolled leaf. However, they have been found inside cantaloupe and summer squash in rare instances. Adults usually emerge after seven to 10 days.
Adults are brownish-yellow moths that have a rounded brush of hairs at the rear of the body.
Moths are active at night. The squash beetle feeds upon the leaves of cucurbits. All other lady beetles are beneficial because they feed on insect pests such as aphids and scale insects. Spider mites require a miticide such as Kelthane. Apply Kelthane twice, five to seven days apart for adequate control.
