Size: Females spiders are 0.2 – 0.5 inches (0.5 – 1.2 cm) and males are smaller with around 0.1 inches (0.2 cm).

Color: Spiders of the genus are generally bright, coming in colors of orange, silver, green, and brown. However, the females have distinct black, yellow, and silver markings, distinguishing them from their male counterparts.

Spiderlings

After overwintering, spiderlings come out and disperse in the spring season.

The Web

Their web is similar to orbs slanting at a 45° angle. The spider chooses to sit in the middle of the web, facing downwards.

Are Spiders of the Leucauge Genus Venomous

Their bite has a low venom, causing not more than skin irritation to people with allergies.
