Fiddleback spider is another name of a brown recluse spider. The recluse spider was named as such because of its markings on the dorsal side of its cephalothorax. The markings also include a black line that looks like a violin with neck points to the rear of the spider. Another name of the brown recluse spider is “violin spider”.
What do they look like?
The fiddleback spider or the brown recluse spider grows to between 6 to 20 mm but some even exceed 20 mm.
It is colored light to medium brown and sometimes ranges from cream colored to dark brown and even blackish gray. However, its abdomen and cephalothorax may not have the same color.
An adult brown recluse spider can live up to two years with each female capable of producing eggs over a period of two to three months, particularly from May to July.
The resiliency of a fiddleback spider is high and can tolerate up to six months without eating.
A fiddleback spider can build irregular webs which serves as their shelter. The webs can be seen in woodpiles, sheds, garages, closets, cellars and other places that are dry are those which are undisturbed. Those living in human residences prefer hiding in an area with cardboard since it is similar to their natural habitat. They can also be seen in shoes, in bed sheets of beds not often used and also inside dressers including stacked clothing, behind pictures and within working gloves. The brown recluse bites when its dwelling area is disturbed or when it is threatened.
Male fiddleback spiders are usually the hunters looking for insects for preys at night while females usually stay near their webs.
Fiddleback spider bite symptoms
The bite of the fiddleback or brown recluse spider may not initially generate pain but it can be serious.
The bite discharges a potentially deadly hemotoxic venom but most bites are minor without necrosis.
Some bites may result in severe dermonecrotic lesions but rarely does the bite of the brown recluse generate severe cutaneous skin or systemic symptoms.
The systemic symptoms from fiddleback or brown recluse spider bite may include vomiting, fever, rashes, nausea, and muscle and joint pain. Cutaneous symptoms are more frequent than systemic symptoms.
