APPEARANCE

Adult specimens vary in color from dull yellow to tawny, dark brown. Younger spiders are lighter in color than adults. The abdomen of the brown recluse has no stripes or spots. Adults measure approximately 6 to 11 mm in length of body. At the widest leg span, their bodies are roughly the size of a United States quarter.

The most telltale characteristic of brown recluse spiders is the presence of a dark, violin-shaped mark on the dorsum of the arachnid’s light brown or yellowish-brown cephalothorax. The neck of this distinct violin pattern is directed toward the abdomen. Due to this marking, brown recluses are also commonly known as fiddle-back spiders. To positively identify a spider as a recluse, both the eyes and fiddle marking must be seen, since other spiders may possess one or the other characteristic alone.

REPRODUCTION

Female brown recluses generate one to five egg sacs which can contain 31-300 eggs.  Eggs usually hatch in about a month.  Development from egg to adult is approximately a year.

Young brown recluse spiders are slow to grow and may reach maturity within 10 to 12 months. Their development is influenced by factors such as food and weather conditions. However, brown recluse specimens are capable of surviving for extended periods without food or water.
