Watch out for the Hair!

The desert blond tarantula is an arachnid found in parts of the southern United States and northern Mexico.

To defend themselves this species is equipped with Urticating hairs. These are hairs which can be detached and have special barbs which help them to attach to the skin of predators which will irritate them and hopefully distract them from eating the spider.

They are carnivores which will spend their time seeking out invertebrates.

These animals are threatened by vehicle strikes. During mating season males will make large movements which often see them moving across roads.

Read on to learn more about these intriguing invertebrates.

How does the Desert Blond Tarantula produce its young?

Males begin their mating advances by stroking silk lines at the entrance to her burrow.

During mating the male is at risk as the female may eat him to obtain energy to use while raising their young. As soon as mating is complete he will quickly leave to try and escape this.

Females may retain sperm from a mating to fertilize several clutches of eggs. She can retain this until she next sheds her skin.

While females produce a large number of eggs few of these will reach adulthood.

It takes a long time for a desert blond tarantula to reach maturity. Females achieve this around 10 years old while males achieve this at 10-12 years old.

Males will only live a few months after they mate.


What does the Desert Blond Tarantula do during its day?

During winter these animals will plug the entrance to their burrow using soil, rocks and silk. This seals them inside and they will remain largely inactive during the coldest part of the year. They survive during this time using stored fat reserves.

These animals are active by night.

They are considered solitary and will only come together to mate.

Predators and Threats

What stops the Desert Blond Tarantula from surviving and thriving?

These animals are prey for tarantula hawk wasps. These inject the spider with poison and paralyze it. It will then be dragged back to the wasps burrow where the wasp will lays its egg in the tarantula. The eggs hatch and this spider becomes their first food source.

During summer large numbers of males are seen crossing roads as they attempt to find a mate making them vulnerable to vehicle strikes.

When threatened these animals can use hairs on their abdomen to defend themselves. They will detach these hairs which have barbs which help to make them stick in the skin of the predator. These are irritating for the threat.

This species is a popular pet in some areas of the world.
