How to Identify Black and Orange Caterpillars

Black and orange caterpillars are the larval stage of moths and butterflies. These creatures have a fat worm-like body with black and orange stripes. The furry orange bodies with black bands also have tufts of spiny hairs sticking out.

You can identify black and orange caterpillars from the worm-like body with bristles, stumpy-looking prolegs, head shape, and six legs. But there are some scary-looking black and orange fuzzy caterpillars with black spikes on their back and heads.

These caterpillar types eat specific plants and go through several instars. A juvenile caterpillar looks different from a mature caterpillar about to enter the pupa stage. For instance, a juvenile mourning cloak caterpillar may appear as a stinging caterpillar despite being harmless.

Some orange and black fuzzy caterpillars are poisonous to some animals since they feed on ragwort and store the poison in their bodies. If small rodents or birds consume these caterpillars in large amounts, the poison will be fatal.

Most black and orange grubs measure less than an inch to six inches long. Besides that, they belong to the order Lepidoptera. There are over 180,000 caterpillar species that turn into different types of moths or beautify butterflies.
