6 Legged Animal List (12 Examples)

1. Butterflies

Butterflies are one of the most beautiful insects with 6 legs.

They have a long organ in their mouths called a coiled proboscis that they use to drink and antennae shaped like clubs. Butterflies have two sets of three legs located on each side of their bodies, with each leg having five separate parts.

Though all butterflies mate up to twice a year, they eat different types of nectar from plants. They form cocoons that keep them safe from predators until they become butterflies.

2. Fleas

One of the biggest nuisances to pet owners is fleas. These tiny insects attack both dogs and cats. Your pets can bring them inside where they will live and produce more fleas.

Their legs have durable claws that help them attach to your pet and keep them stable as they need. When left untreated, fleas can cause a condition called flea anemia that can lead to death in pets.

Signs of flea anemia may include lethargy and trouble eating. Using products to treat flea eggs and adults will keep your home and pets safe.
