Spider vs. Scorpion Identification

Spiders and scorpions are considered to be two of the most feared animals. Both of these creatures are classified as arachnids and, along with mites, ticks and harvestmen, possess eight legs. They also both have two body segments, including the cephalothorax and the abdomen. Both develop through successive stages, starting with eggs from which hatch miniature versions of the adults that molt and grow in size. Their speed of growth and development varies. Their behavior and habits are also somewhat similar. Both are predatory and obtain nutrition by catching and consuming other animals such as insects.

Despite the similarities, there are significant differences between spiders and scorpions. Spiders have a pair of fangs that they use to inject venom. Scorpions lack fangs but instead have a stinger located at the end of their tail to inject venom. Scorpions also have a pair of pinchers which are modified pedipalps. Spiders lack pinchers of any kind. Scorpions lack spinnerets and therefore do not produce silk, whereas spiders do.

Both of these creatures can invade indoors. If you have questions about spiders or scorpions, contact a pest control professional.
