it’s a species of beetle in the leaf beetle family, Chrysomelidae. It is natve to the Americas.

measuring from 5–7 mm in length. They are variable in color from reddish-brown with black spots to brilliant, Mirror gold, earning it the nickname "goldbug".

Elytral margins are expanded and nearly transparent.
The color changes through its development, during mating, and during times of disturbance, such as when it is touched by a human researcher. Scientists have not examined the color-change mechanism in this species. However, color change in the related golden tortoise beetle occurs when this beetle's elytra hydrate and dehydrate.

Adults of both species can turn from shiny gold through reddish-brown when disturbed.

Female Golden tortoise beetles lay clusters of eggs on stems and on the undersides of host leaves. A spiny, yellowish or reddish brown larva emerges from its egg in 5 or 10 days. A larva accumulates its shed skins and frass on a structure called an anal fork, which it positions over its body as a fecal shield, evidently hiding the larva from predators. This is usually effective against smaller insect predators such as ants, but not larger ones, such as hemipterans. After two to three weeks, a larval Golden tortoise beetle becomes a spiny brown frass-covered pupa, and in one through two weeks later it emerges as an adult.


The beetle will consume foliage of plants including bindweed, morning glory and sweet potato. Both adults and larvae feed on foliage.

They will also play dead if a Predator is near or when disturbed.
