Wolf spider description
| Kingdom | Animalia |
| Phylum | Arthropoda |
| Class | Arachnida |
| Order | Araneae |
| Family | Lycosidae |
| Genus | Pardosa (1) |
All wolf spiders are agile, fast-moving ground predators. This species is brownish in colour, and males are typically darker than females, with more distinct markings (3). Like all spiders they have four pairs of legs. In front of the walking legs there is also a pair of leg-like palps, which are used in males for sperm storage (4); in spotted wolf spider males, these palps are black and covered in dark hairs (3). On the head there are eight eyes arranged in three rows; the first row comprises four small eyes, the second contains two larger eyes and the third row has two medium-sized eyes (4).

Wolf spider biology
This wolf spider does not make a web, but hunts its prey during the day by sight, chasing insects and leaping on them.
Males reach maturity from spring to mid-summer and can be seen performing courtship displays to females on sunny days, waving the legs in a specific 'routine'. The female lays her eggs soon after mating and carries them around in a silk cocoon attached to her body by the spinnerets at the end of the abdomen. After hatching, the spiderlings cling to the female's body for around a week before they disperse (5).

Glossary
- Abdomen
- In arthropods (crustaceans, insects and arachnids) the abdomen is the hind region of the body, which is usually segmented to a degree (but usually not visibly in spiders). In crustacea (e.g. crabs) some of the limbs attach to the abdomen; in insects the limbs are attached to the thorax (the part of the body nearest to the head) and not the abdomen. In vertebrates the abdomen is the part of the body that contains the internal organs (except the heart and lungs).
- Cocoon
- A sheath of silk, which is spun around the pupae of some insects (a pupa is a stage in an insect's development, when huge changes occur that reorganise the larval form into the adult form. In butterflies the pupa is also called a chrysalis).
- Palps
- In invertebrates, palps are sensory appendages located near the mouth.
- Spinnerets
- Tube-like, movable silk handling structures found at the tip of the abdomen (the hind region of the body) in spiders. There are four pairs of these organs, but in most species there are fewer (usually three). The silk is produced by the silk organs as a liquid, which passes through the spinnerets and is put under tension until the silk becomes a solid thread.
