Physical characteristics: This species measures 0.19 to 0.31 inches (5 to 8 millimeters) in length. Their bodies are whitish or light brownish. They are impossible to identify without examination through a microscope.

Geographic range: The true range of this species is unknown because it is often confused with other closely related species.

Habitat: This species lives in leaf litter and rich soil. It is also found in agricultural fields and greenhouses.

Diet: The garden symphylan eats vegetable material, especially small roots and rootlike parts of funguses.

Behavior and reproduction: The adults are especially quick when threatened.

Males leave sperm packets on the ground for females to pick up. Eggs are laid in masses, each mass containing up to twenty-five eggs. The larvae (LAR-vee), or young, hatch with six or seven pairs of legs and add a new pair of legs with each molt.

Garden symphylans and people: This species is sometimes a serious pest in fields, gardens, and greenhouses and hothouses.

Conservation status: Garden symphylans are not considered endangered or threatened. ■
