As dwarf tarantulas, they reach a modest size of 2-3 inches in body length and a leg span of 4-5 inches, with females generally larger. 

What Pumpkin Patch Tarantula Like to Eat or Hunt?

Hapalopus formosus, like their tarantula cousins, are insect eaters in the wild. They patiently wait to ambush their prey, which includes crickets, roaches, grasshoppers, and beetles.

These insects provide essential nutrition, with crickets being a staple. At the same time, wild tarantulas might eat other insects.

It is best to avoid offering spiders, worms, or millipedes to captive tarantulas due to potential risks.

Tailor the size of the insects to fit the tarantula’s size; offering smaller portions for the tinier ones or breaking larger insects into bite-sized pieces is good to go.


The Hapalopus formosus resides in the vibrant rainforests of northwestern Colombia. In this natural habitat, the climate is warm and humid, with temperatures ranging from 75°F to 80°F and humidity exceeding 70%.

Preferring an arboreal lifestyle, they construct homes among the trees, utilizing burrows or webs for shelter and hunting.

From leaf litter on the forest floor to bromeliads on branches, these tarantulas find diverse niches within their habitat. They lead solitary lives and only interact with each other during the mating season.


The Hapalopus formosus is known for its gentle nature and notable speed and does not have venom that is harmful to humans.

Even though they can be a bit nervous or skittish, and they have tiny irritating hairs on their bodies for protection, they are generally calm.

These tarantulas like to create detailed webs, and you can often find them outside of their burrows, which they seem to enjoy.

So, despite being a little jumpy and having protective hairs, they are not aggressive and can be quite interesting to observe as they go about their web-making and explorations.

Reproduction, Babies, and Life Cycle:

During mating season, males venture out in search of females, engaging in a unique courtship dance.

After successful mating, females lay about 400-500 and guard their silk-wrapped egg sacs, showing maternal care uncommon among tarantulas. 

Around 6-8 weeks later, tiny versions, called slings, emerge, gaining adult colors within days.

Unlike other tarantulas, pumpkin patch mothers tend to their young Pumpkin patch slings, who stay briefly before leading solitary lives. Molting is their growth secret, occurring more frequently in slings. 

Females reach maturity in 5-7 years, males slightly earlier. Notably, pumpkin patch slings exhibit early adult coloration.


These docile tarantulas live 7-10 years (males) or up to 15-20 years (females). 


Snakes, lizards, birds, and larger spiders hunt Hapalopus formosus. The tarantula hawk, a formidable wasp, poses a significant threat. 

Bite and Venom: 

Hapalopus formosus are generally docile, rarely biting unless provoked. Their bites, described as a bee sting or sharp pinch, are uncomfortable but not usually life-threatening. 

While the venom is mild and primarily used for prey immobilization, seeking medical attention for possible allergic reactions or infections is advised.

Handle them with caution and respect the tarantula’s personal space to ensure a safe and stress-free interaction.

Pumpkin patch tarantulas are usually calm, not too big (2-3 inches), eat well, have easy habitat needs, and live a decently long time (7-15 years), making them an easy and lasting pet choice for beginners.
