Look for a few species of crab spiders in Florida, including:Ĭrab spiders aren’t considered dangerous for humans or their pets. Most often, they wait with their front legs pulled back, helping make them look like crabs. Instead of spinning webs, these crabs hide in opportunistic locations and ambush their prey. Crab SpidersĬrab spiders get their name from the way they look and how they sit. They’re commonly found in yards and gardens and are great to have around because they eat nuisance insects. While their bite can be painful or cause discomfort, orb-weaver spiders are not considered a threat to humans. The spines are black and red, with a big yellow abdomen, a red underside, and an orange head and legs. Their legs and spines tend to be black with white, orange, or yellow coloring on their backs.Īrrow-shaped orb-weavers have abdomens shaped like flint arrowheads. Spinybacked orb-weavers have six distinct points on their abdomens and can be a wide variety of colors. Most of their body is an orangish color and they’re easy to distinguish from other spiders. The star-bellied orb-weaver for example has a large, crown-shaped abdomen. Many orb-weavers have very distinct shapes and color patterns. Multiple species of orb spiders can be found in Florida including: Many of them tend to build a new web every day, consuming the old web and then resting for an hour or two before constructing the new one. Orb-weaver spiders get their names from the spiral-shaped webs they build. Rarely can a bite result in death, but serious skin damage, nausea, and muscle pain can occur. They can go unnoticed until symptoms appear, as the bites themselves are nearly painless. Recluse bites have a necrotic effect that can damage tissue surrounding the bite location. Populations can be found in single buildings within Florida, but they have no known stable populations. They are especially common in firewood piles and hide under logs and rocks in natural environments. Like widow spiders, recluses tend to love dark areas. They average around 6 mm (1 inch) in body length. They have only six eyes, arranged in three pairs on their face. The surest way to identify a recluse spider is by their eyes. While they tend to be brown in color, both thor marking and overall color can vary drastically. Three species of recluse have been seen in Florida, including the brown recluse, Mediterranean recluse, and Chilean recluse.īrown recluse spiders tend to have a dark violin-shaped marking on their abdomen. Recluse spiders are not native to Florida, but they have been observed throughout the state and are known to establish small populations in scattered locations. The bites are generally not fatal for adults but can cause nausea, difficulty breathing, burning pain, and body shakes. For some, they may experience mild symptoms, but for others, the symptoms can be severe. Venom from widow spiders can affect people differently. They build conical webs in the corners they hide in. In nature, they tend to hide under rocks or logs, but widow spiders adapt easily to urban environments and can be found in outbuildings or other manmade structures. Widow spiders tend to prefer dark, confined spaces. Most females range from 8 to 15 millimeters (0.8 cm to 1.5 cm), while males can be as small as 2 millimeters (0.2 cm). Generally, they have shiny black abdomens and red markings, but widows can also be pale or have lateral stripes. Widow spiders typically share similar color patterns and markings. Southern black widows, Northern black widows, red widows, and brown widows (introduced) can all be found in the Sunshine State. Three widow species are native to Florida, with a fourth being accidentally introduced.
