Field Guide

Whitebanded fishing spiders are often seen on tree trunks, walls, or other vertical surfaces, sometimes far from water. The coloration and markings can vary, but many individuals have an olive-green cast that helps them blend in with mosses and lichens. Note the bristly legs.

The white micrathena has 2 short pairs of tubercles and a white abdomen with a few distinct black blotches on the upper side. In an odd way, it looks like it's wearing a turban. This is one of three Missouri species of micrathenas, also called spiny orbweavers.

A widespread species, the barn spider commonly builds its webs in woods and on the eaves of barns, houses, and similar structures.

The arabesque orbweaver is a common orb-weaving spider in Missouri. The coloration is quite variable, but the slanting dark marks on the abdomen help to identify it.

The dotted wolf spider has a solid brown stripe running down the middle of the abdomen, seen from above. Like other wolf spiders, females have strong maternal instincts, carrying their spiderlings around on their back until they can be on their own.

A speckled wolf spider usually seems larger than it actually is. It's one of Missouri's more common species of wolf spiders. Mothers have remarkable maternal instincts and are often seen carrying their young around on their abdomen.

The rabid wolf spider, despite its scary name, is harmless to people and is absolutely not rabid. It commonly hides in leaf litter and sometimes gets into houses.

The openfield orbweaver is a common nocturnal orb-weaving spider in Missouri.

The marbled orbweaver is sometimes called the “pumpkin spider” because its rounded abdomen is sometimes bright orange. The color and markings can vary greatly.

Armored harvestmen have spines on their fingerlike mouthparts (pedipalps). Unlike other harvestmen, members of this suborder of so-called daddy longlegs do not usually have long legs.
