Their larval form (caterpillar) are popularly called 'inchworms' because of the way they walk. They are a part of the Measuringworm Moth family. They only have front and back legs that help them walk so in order to move their long bodies forward, they have to pull both sets of legs close together and them push them apart. This type of caterpillar is popular thanks in part to the iconic children's book "The Hungry Caterpillar". If the caterpillar feels threatened, it will straighten and stretch its body out at an angle while on a stem, making it look like a short, stubby twig on a branch.
Adults prefer woodland forests and are attracted to lights at night, like most moths. Caterpillars feed on short, woody plants and blackberry plants.
