Tarantulas in the Dominican Republic, Should You Worry About Finding One?

Tarantula in Dominican Republic

The scientific name of the tarantula known as “cacata” in the Dominican Republic is Phormictopus cancerides. This species of arachnid is native to the Caribbean. It is also one of the largest in Latin America.

Cacatas spend the day hiding in caves or under rocks, and at night they go out to look for food. And their behavior is very violent.

To defend themselves, they have long and powerful fangs, they shake the hairs off their abdomen and stick them into the human skin, producing intense irritation.

The Cacata is one of the most feared arachnid insects in the Dominican Republic, if you are wondering the chances of meeting one I can tell you, in my personal experience I have been living in the Dominican Republic for decades and I have never seen a “Cacata” or Tarantula anywhere.

Tarantulas are scary looking and intimidating, but if your concern is meeting one in the Dominican Republic, even though they exist in the country, the chances are almost zero.

Although I must say that I am a city person and the cacatas are more on the countryside, anyway I have visited villages and rural communities of the Dominican Republic and I have not had any kind of encounter with cacatas.

Actually, if you come to the Dominican Republic the chances that you will find a tarantula are extremely low.

The chances of finding a tarantula may be a little higher if you visit remote rural communities, in any case, you should not be unreasonably afraid of them.

Tarantulas are simply not a common species to see in the Dominican Republic, and apart from this, they are very elusive and run away from human contact.

They inhabit tropical forests and some rural communities. Large numbers of this species of land spider have also been recorded in the rain forests of Brazil.

Adults can measure between 7 and 8 inches in diameter.

It also stands out for its striking coloring that can appear to be bronze or almost purple. Males tend to be more colorful than females.

Males have a short life span of 18 to 24 months, while females can live more than 20 years.

They go out more frequently in the months of October and November and at night.

During the day, they hide in caves or under rocks, and come out at night in search of food. They exhibit quite aggressive behavior. They defend themselves by using their powerful fangs that can be more than 2 centimeters long or by kicking stinging hairs from their abdomen.

Cacatas feed on insects, birds, lizards and some small mammals. Their fangs pierce the body of their victim, and inject venom that paralyzes and breaks the tissue of the prey, allowing the tarantula to suck out the inside of the prey.

Tarantulas are scary looking and intimidating, but if your concern is meeting one in the Dominican Republic, even though they exist in the country, the chances are almost zero.

Although some people are convinced that their bite kills, their venom is not lethal, but can be very painful for human beings. Despite the low probability of finding one, It is recommended that you be very careful when coming into contact with these arachnids.

Tarantula Endemic to the Dominican Republic

Dominican Blue leg tarantula

Phormictopus cancerides is a Dominican Republic endemic tarantula and one of the two most common, the other is Citaracanthus spinicrus found in much of the country. Both the male and female have purple, blue and violet iridescences.

Generally the females tend to lose a little color and turn brown, this happens because after reaching maturity, which takes about 30 months.

The males copulate and die between the jaws of the females or at most a year later, while the females continue to grow and shed their skin 1 or 2 times a year, that’s why when so much time passes between one shed and another they lose their shiny black color with precious iridescences.

Their breeding seasons are from September to November and from April to June, but these seasons are getting longer. As for the quantities of eggs, they lay about 150.

In the Dominican Republic there are more than 30 species of Migalomorphous spiders (tarantulas), some are very small and live very hidden.
