Identification

Reticulated pirate spider is a small to medium-sized, eight-eyed spider. It occurs across North America. Females are to 3 16 (4.2 to 5 mm) long. Males are slightly smaller, (3.5 mm) long.

The covering (carapace) of the front part of the body (cephalothorax) is longer than wide, has a low profile when viewed from the side, and is armed with long curved spines. It is pale yellow with black markings, including four black lines. The lines are wide, irregular, and have branches connecting them. They extend backward from the eyes and converge on a groove in the thorax.

There are eight eyes in two rows. The last part (cymbium) of the finger-like mouthpart (palp) has a spine at the tip but no other spines near the tip. The palp on the female has a claw.

The abdomen is high in front and yellow but mostly covered with black markings. It is armed with long straight spines.

As with all spiders, there are four pairs of legs. The first pair is 1½ to 1 times as long as the fourth pair. The legs are very long and slender. They are pale with black spots and bands, and are armed with long spines. The third segment (femur) is not dark near the tip. It has numerous black spots on the underside but does not have two distinct black lines. The fifth segment (tibia) and sixth segment (metatarsus) each have a rows of long, slightly curved spines with a row of much shorter spines between them.

Glossary

Carapace

The hard, upper (dorsal), shell-like covering (exoskeleton) of the body or at least the thorax of many arthropods and of turtles and tortoises. In crustaceans, it covers the cephalothorax.

 

Cephalothorax

The front part of a spider’s body, composed of the head region and the thoracic area fused together. Eyes, legs, and antennae are attached to this part.

 

Femur

On insects and arachnids, the third, largest, most robust segment of the leg, coming immediately before the tibia. On humans, the thigh bone.

 

Palp

Short for pedipalp. A segmented, finger-like process of an arthropod; one is attached to each maxilla and two are attached to the labium. They function as sense organs in spiders and weapons in scorpions. Plural: palpi.
