Cyclocosmia loricata

Physical Description and Identification

Adults

Size: 2.8 cm (1.1 in)

Color: These spiders are black, with their legs showing shades of brown as well.

Other Characteristic Features: Like all other Cyclocosmia spiders, they have a flat abdomen which appears similar to that of a coin.

Eggs

The eggs are rarely seen as they are laid inside a burrow, which the female protects with her abdomen.

Spiderlings

They stay inside the tunnels until they are mature enough to leave, remaining under their mother’s protection until then.

The Web

These spiders do not have sufficiently strong webbing, instead burying themselves underground. They then either cover these holes with a trapdoor or use their abdominal shield to clog the entrance temporarily to prevent predators from attacking.

Is the Cyclocosmia loricata Spider Venomous

Though their bites can be painful, the spiders themselves are very timid and avoid venturing out of their homes, if at all. If bitten, the pain subsides quickly, and there are no lasting effects from the venom.

Quick Facts

Lifespan 5-10 years
Distribution Mexico
Habitat Tropical and sub-tropical regions
Common Predators Wasps
Diet Ants, beetles, cockroaches, and moths
