Tarantulas in Texas are popping out of the earth. Here's what they're looking for.

Clusters of tarantulas are popping out of the earth in Texas looking for love − an annual occurrence during the summer in the Lone Star State.

In what's called “one of the most spectacular spider events in Texas," by a Texas A&M field guide, male tarantulas exit their burrows to look for female mates.

The spider mating takes place starting in May and runs through July.

According to the National Park Service, there are 14 identified tarantula species in Texas with the most known being the Texas brown tarantula.

What do tarantulas look like?

Tarantulas are easily identified by their large size and females can lay up to 1,000 eggs in their burrows, according to park service officials.

Known as the heaviest spiders by weight, tarantulas have a body length of about 1 ½ inches, according to a Texas A&M field guide. Typically, the head, thorax and legs are dark brown and the abdomen is brownish black.

Their colors vary and change after a molt.

In Texas, the university said, male tarantulas usually live seven to eight years, while females can live to 25.

How do tarantulas mate?

David Moellendorf, the store manager at ZooKeeper Exotics, told Texas TV station KTVU, male tarantulas live underground for five to seven years and after living underground for so long, molt their skin one last time and go out looking for love.

They "use chemoreceptors on their feet, and they can taste," Moellendorf told the Austin-based outlet. "And if there's any silk or anything like that from a female around, the male is able to sense that. He will start looking in that area."

After finding a partner and mating, females sometimes eat the father of their offspring for added protein "to create larger eggs."

"The egg sac is retained in the burrow, guarded, and usually held by the female," park service workers said. The eggs hatch within two months, and once they leave the egg sac, spiderlings may stay with the females for at least three days before dispersing. 

What do Texas tarantulas eat?

Tarantulas usually remain in their burrow waiting for prey to come by but "may move a few meters out to forage when necessary," according to the university.

They feed on crickets, June beetles, ground beetles, grasshoppers, cicadas and caterpillars.

Does a tarantula bite make you sick?

Texas tarantulas typically remain in their burrows, park service officials said. The spider's venom doesn't usually make a person sick, but their bite is painful.

If disturbed, tarantulas maneuver to face the threat, raise up on their back legs and stretch out their front legs in a threatening defense, per park service officials. They also have urticating hairs which are kicked off at the spiders’ attacker and can cause irritation if they come in contact with skin.
