Spiders' legs are made up of seven segments. Starting from the body end, these are the coxa, trochanter, femur, patella, tibia, metatarsus and tarsus. The tip of the tarsus bears claws, which vary in number and size. Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws.
Diagram of a spider leg and pedipalp – the pedipalp has one fewer segment. Arachnid legs differ from those of insects by the addition of two segments on either side of the tibia, the patella between the femur and the tibia, and the metatarsus (sometimes called basitarsus) between the tibia and the tarsus (sometimes called telotarsus), making a total of seven segments.
From the proximal end (where they are attached to the body) to the distal, they are: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs.
Dionychous: With two claws on the tarsus of each leg; [6] a feature of spiders in the clade Dionycha; Dorsal groove: see fovea; Dorsum: The upper (dorsal) portion or surface of the body or abdomen; the adjective dorsal may be applied to the upper portion or surface of any part of the body; see ventrum
The part closest to and attaching the leg to the cephalothorax is the coxa; the next segment is the short trochanter that works as a hinge for the following long segment, the femur; next is the spider's knee, the patella, which acts as the hinge for the tibia; the metatarsus is next, and it connects the tibia to the tarsus (which may be thought ...

The legs are short, stumpy, yellow with brown patches and covered with brown and white hairs. The tarsus has a spade-like appendage. The spider has a large oval heavily-sclerotized epigyne that has a very narrow tube-shaped pocket.
“Spiders are beneficial bugs that help control other pest insects such as flies, adult mosquitoes, ants, etc.” Capture and release can look like using a cup and a piece of paper to capture and ...
