The giant leopard moth starts out as a prickly black caterpillar.

It has orange markings across its body and although its prickly fur appears to cause injury, these bristles on their bodies aren’t urticant, which means they don’t splinter off when touched. You could touch it gently with your fingertips—although, it may curl up in defense. Another defense mechanism giant leopard moths use is the release of yellow fluid from their thoraxes. After a period of hibernation, the caterpillar emerges as the giant leopard moth, to enjoy a nocturnal life.

Species, Types, and Scientific Name

The scientific name for the giant leopard moth is Hypercompe from the H. scribonia species. It is also commonly referred to as the tiger moth. It’s from the Erebidae family, which is a family of moths from the superfamily Noctuoidea. There are over 70,000 species of moths that form this superfamily—they refer to “night owl” moths that can be found traveling throughout the night.

This species of moth was previously recognized as part of the Arctiidae family. However, they were reclassified because of their nocturnal lifestyles. The males are highly attracted to bright lights at night, while the females are less commonly found swirling about lights with their male counterparts.

The giant leopard math has two subspecies:

  • H. s. scribonia
  • H. s. denudate

The name doesn’t lie—these moths are as large as a human palm. They have a wingspan of three inches and the males are almost twice as large as the females. They’re easy to spot because of their unique black and white spotted pattern. As “wooly bear” caterpillars, they hibernate during the winter months and spin into cocoons during springtime.


Giant leopard moths have a beautiful, easy-to-spot appearance. The males and females have slightly different appearances, but both have large white wings peppered with black dots. Some of the dots are solid, while others are hollow. On the top side of their abdomens, you can spot a dark blue, iridescent color with some orange markings.

The bottom side of their abdomens is like their wings—white with black spots. Their legs are also black and white but instead of spotted, these colors are banded. Male leopard moths have a distinctive yellow line on each of their sides.

These moths can sometimes be spotted living together with other moths on a tree. However, these are solitary creatures, and they don’t typically live in groups. However, the males and females come together to mate. Their average litter size is about 50 eggs. Their spotted wing design is ideal for helping them blend in with their surroundings and avoid predators.

Prevention: How to Get Rid of Giant Leopard Moths

Giant leopard moths may sometimes be found in areas close to where humans reside, like in gardens or under wood chips where they rest. Since these insects are nocturnal, it’s not common for you to spot one, unless you spend a lot of time outdoors at night. The male moths are attracted to bright lights, so if you intend to spend time outdoors at night, use a bug shield to keep the male leopard moths away.
