The one what hides also seeks in this life-and-death game of ?What's for Dinner?. A Cork-lid Trapdoor Spider digs out a tunnel in the ground using its mouthparts and legs. It places this tunnel close to walkways that are frequently used by bugs, lizards, and small mammals, increasing the likelihood of catching something. Using its silk, the spider creates a hinged lid to cover the burrow. A hinge offers easy concealment for the retreat and ensures the burrow will not lose its lid if thrown open quickly. This trapdoor is made to fit the exact size of the opening, like a cork stopper. Once the spider, hiding inside the burrow, senses a vibration or tremor of a passerby, it flips up the trapdoor, grabs its meal, and drags it down into the retreat to consume it.

This family of spiders comprises smaller and less hairy spiders than Tarantulas, but they come from the same infraorder, so they are distant relatives and may have similar overall features. Females also use the tunnel to lay eggs and raise young spiderlings, but unlike other types of spiders, the mother stays in the nursery, protecting her offspring from parasitic predators like wasps until the spiderlings are able to forge out on their own.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Cork-lid Trapdoor Spider may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Cork-lid Trapdoor Spider. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
