Where To Find Tarantulas In California
All the tarantulas in California are ground-dwelling hunting spiders. They are nocturnal for the majority of their lives, which is why you don't often get to see them.
They live in burrows, only leaving at night to hunt for food, which includes beetles, lizards, mice, spiders, and other insects, including scorpions.
The male will remain in his area until he fully matures, which is anywhere from 5 to 10 years, he then leaves his area to find a mate.
Males only live a few months after maturity, while females can live up to 25 years.
So where can you find tarantulas in California? You will find them in the fall when the male travels sizable distances to find a mate. You often see them during September and October along with grasslands, trails, and roads.
They can often be seen in Malibu Creek State Park, along with the Topanga State Park in Santa Monica.
They have also been seen in the San Gabriel Mountains, Anza-Borrega Desert State Park, the Mojave Desert, and Joshua Tree National Park.
Tarantulas In California
There are 9 tarantula species you may be lucky enough to spot in California, these include:
1. Aphonopelma iodius
Scientific name: Aphonopelma iodius.
Common name: Fresno County blond, desert tarantula, Great Basin blond, Salt Lake City brown.
This tarantula lives in a webbed burrow, which is under the surface in California desert areas. They will obstruct the burrow entrance with their webs, which protects them against predators and the desert heat.
These are also popular pets and go by a number of different names including the Fresno County blond, desert tarantula, Great Basin blond, and the Salt Lake City brown.
2. Aphonopelma eutylenum
Scientific name: Aphonopelma eutylenum.
Common name: California ebony tarantula.
This tarantula is known as the California ebony tarantula and ranges in color from dark brown and ebony to light beige.
Females can grow to a leg span of five inches (13cm), living up to 25 years.
Males, which are smaller than the female, only leave their burrows to search for a mate when they reach sexual maturity, which is anywhere from 8 to 12 years. Males die a few months after finding a suitable mate.
Females have large abdomens and fangs. They are also often lighter in color than males.
When they feel threatened, they shed spiky hairs on the abdomen, as a defense mechanism.
As they age, older spiders will have a different color spot on their backs and their abdomens are hairless or missing hairs.
These tarantulas spend most of their time in their burrows, waiting for prey to come close to them. The spider then comes out of the hole and catches the prey.
3. Aphonopelma steindachneri
This tarantula is common in California, but not often observed due to it preferring to hide in its burrow until suitable prey passes by.
