Summary
Phalangioidea is a significant superfamily within the harvestman suborder Eupnoi, containing numerous species that are integral to the ecosystems they inhabit. They are characterized by their unique morphology and ecological roles as decomposers.
Physical Characteristics
Harvestmen within the superfamily Phalangioidea typically have elongated bodies and long, slender legs. They lack the constricted waist found in some other arachnids, giving them a more rounded appearance.
Identification Tips
Look for elongated bodies with long legs and fused segments. They may also exhibit a variety of color patterns, though they generally lack the ability to produce silk unlike spiders.
Habitat
Phalangioidea species are commonly found in a range of habitats including forests, grasslands, caves, and leaf litter.
Distribution
This superfamily has a wide distribution across North America, particularly in Greenland, Canada, and the U.S.A. and extends through regions in Mexico as well.
Diet
Most harvestmen in the Phalangioidea are omnivorous, feeding on decomposing plant material, small insects, and detritus.
Life Cycle
The life cycle includes egg, juvenile, and adult stages. Juveniles resemble adults but are smaller and undergo several molts before reaching maturity.
Reproduction
Reproduction typically involves male-female courtship, where males perform a 'dance' to attract females. After mating, females lay eggs in suitable habitats.
Predators
Predators include birds, small mammals, and various insectivorous species that forage in their habitat.
Ecosystem Role
Phalangioidea play a crucial role in the ecosystem as decomposers, helping to break down organic material and recycle nutrients back into the soil.
Collecting Methods
- Hand collection
- Pitfall traps
- Suction sampling
Preservation Methods
- Ethanol preservation
- Drying specimens
- Freezing for short-term storage
Evolution
Phalangioidea contains diverse lineages among the harvestmen, showcasing adaptations that allow them to thrive in various ecological niches.
Similar Taxa
- Phalangodoidea (subfamily)
- Laniatores (suborder)
Misconceptions
Often confused with spiders, they are not spiders. Harvestmen are a distinct order within arachnids and do not produce silk or show web-building behavior.
