The color differences between the male and female Dimorphic Jumping Spider are profound to us, but completely natural to them.
Dimorphic literally means 'two forms'. This is true of this aptly named species of Jumping Spider. The male may be black with yellow legs, or tan with red marks on its abdomen. The two variants looks completely different. The female more closely resembles a paler version of the tan male. The body is covered with short hairs. Mature males have pedipalps in front of the face that might look like antennae or a short pair of legs. They help transfer sperm to the female during mating.
Like all spiders in the Salticidae family, the Dimorphic Jumping Spider can hop, pounce great distances in the blink of an eye. This ability helps it ambush insect prey as well as escape from encroaching threats. The spider is small, but the colors and quick movements make it more conspicuous than other jumpers.
Scientific Name: Maevia inclemens
Size (Adult; Length): 7mm to 10mm (0.27in to 0.39in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
Pedipalps: Small appendages near the mouth used as taste and smell organs.
Cephalothorax: Contains eyes, head, mouthparts, and legs.
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).
