Harvestmen

Phalangium opilio

Description:

Brown and black spider with the two body segments fused. The legs are very long. Third image show size comparison with finger. "Males have a large spur or "horn" projecting from the anterior surface of the first cheliceral segment; females do not have this feature. Males also tend to have long, thin pedipalps relative to those of other harvestmen. Both sexes have small tubercule-mounted spikes on the anterior surface of their body, in-between the top of their chelicerae and the anterior end of the dorsal surface of the body."

Habitat:

On concrete bridge along coast. This species is invasive in North America. "Due to its extensive range and ubiquity in anthropogenic habitats, this species is the single-most studied opilionid."

Notes:

Yay, my first Harvestmen!
