Overview

The Dwarf Chilean Flame Tarantula, previously known as Euathlus sp. “Red” or “Flame” is a spider species that belongs to the Theraphosidae family. This species is popular among beginner tarantula hobbyists due to its relatively small size, docile nature, and bright coloration. In addition, it’s famous for its slow growth rate and longevity, as it can live up to 12-15 years. As the name suggests, it’s native to Chile and can be found in dry scrubland areas.

 

As a ground-dwelling species, Dwarf Chilean Flame Tarantulas are more inclined to burrow and remain hidden. They exhibit a stunning, velvety red coloration that has garnered them the common name ‘Flame Tarantula.’ Adult females typically have more vivid coloration than males, and the intensity of this coloration can vary between individuals. Despite their intimidating appearance, these tarantulas are known to be extremely docile and rarely present a threat to humans.

 

Arachnid aficionados often utilize scientific nomenclature to precisely identify their favored species, though the situation becomes somewhat convoluted when discussing the Chilean flame. Many spider species bear striking resemblances, with minor discrepancies in attributes such as size and color that often spark discussions about their taxonomical categorization. This issue arose with the Chilean flame, which only recently was classified as its species, Homeomma chilensis, instead of Euthlus sp red, a taxon potentially comprising a multitude of spider variants, each potentially representing a distinct species.

Physical Description:

Chilean Flames are identified by the unique patch of fiery orange hair at the junction of their abdomen and carapace. This vibrant coloration is the sole bright hue on their bodies, with the remaining four being a rich brown to facilitate camouflage within their environment. Given their diminutive size, this species is categorized as a dwarf spider. An individual of this species will only reach a maximum size of between 8 and 9 centimeters.

Mature females tend to have a more vivid coloration than males, who are more subdued in color and have a slightly larger body size. Like all tarantulas, they have eight legs, two body segments (the cephalothorax and abdomen), and a pair of pedipalps. They also have two primary types of hairs: urticating hairs, which they can fling at threats, and tactile hairs, which help them navigate their environment.

Lifespan: Male: ~3 Years || Female: ~12 Years

Weight: Male: 0.07-0.09 lbs (30-40g) || Female: 0.1-0.14 lbs (45-65g)

Length: Male: 2.9-3.2 inches (7.3-8.1 cm) || Female: 3.2-3.5 inches (8.1-9 cm)

Top Speed: Unknown, but said to be extremely fast runners

Native Habitat:

The Dwarf Chilean Flame Tarantula is native to the scrubland areas of Chile. These areas are typically dry with sparse vegetation, providing the tarantula ample opportunities to burrow and hide from predators. They are more comfortable on the ground and usually found in caves or under rocks.

This species is adapted to a relatively dry climate, but it’s essential to maintain some level of humidity in their environment. In their natural habitat, they often create burrows in the ground, which they use for shelter, hiding from predators, and ambushing prey.

Diet & Feeding Habits:

Dwarf Chilean Flame Tarantulas, like other tarantulas, are naturally predatory, mainly insectivorous. They primarily feed on a diet of small invertebrates such as insects, particularly crickets, mealworms, and cockroaches. These tarantulas are ambush predators, meaning they typically wait for their prey to come within striking distance before launching a quick and deadly attack.

In captivity, it’s common for keepers to feed them a diet of gut-loaded crickets, which provides the tarantulas with necessary nutrients. It’s important to note that they eat less frequently as they age, and adult tarantulas may only require feeding once a week or even less. Overfeeding can lead to health issues such as obesity and a shorter lifespan.

Mating Behavior:

Mating Description:

Dwarf Chilean Flame Tarantulas have a relatively complex mating process. After reaching maturity, males will begin to produce sperm webs, which they then charge with sperm. Once this process is complete, the male will seek out a female, performing a series of ritualistic movements to signal his intentions and to prevent the female from mistaking him for prey.

Females will often respond with receptive movements, allowing the male to approach. The male will then use his pedipalps to deposit his sperm into the female’s reproductive organ, the spermathecae. After mating, the male will typically make a swift exit to avoid being eaten by the female. The female will subsequently produce an egg sac, which she will guard fiercely until the spiderlings hatch.

Social Structure Description:

Dwarf Chilean Flame Tarantulas are solitary creatures that only come together during breeding. Males, once mature, will leave their burrows in search of females to mate with. After mating, they often leave quickly to avoid being eaten by the female.

These tarantulas are primarily concerned with individual survival outside the breeding season. They each maintain a burrow or shelter, which they do not share with others. Interactions between individuals, except for mating, usually result in aggression.

Conservation Status:
Population Trend:
Wild: Unknown || Captivity: Unknown

As of the latest data cutoff in 2021, the specific population numbers for the Dwarf Chilean Flame Tarantula in the wild are not known. The species is not currently evaluated on the IUCN Red List.

The main threats to the population are habitat loss and degradation due to urban development and agricultural expansion. The illegal pet trade may also impact the species, but the extent of this effect is currently unclear. Further research is needed to accurately assess the population status of this tarantula species.

Population Threats:

The primary threat facing the Dwarf Chilean Flame Tarantula is habitat loss due to urban expansion and agricultural development. The tarantulas’ native scrubland habitats are being increasingly converted for human use, which disrupts their living and hunting grounds.

Furthermore, the illegal pet trade may also significantly threaten the population. These tarantulas are popular among hobbyists for their vibrant coloration and docile nature, so they are often caught and sold illegally. However, the extent to which this affects the overall population is still not completely understood.

Conservation Efforts:

As the Dwarf Chilean Flame Tarantula is not currently evaluated on the IUCN Red List, specific conservation efforts targeting this species are unknown. However, general conservation strategies that could benefit this species include habitat preservation and enforcing laws against illegal wildlife trade.

In addition, captive breeding programs could be beneficial in reducing the pressure on wild populations from the pet trade. These initiatives require proper monitoring and regulation to ensure that they contribute to the conservation of the species and do not inadvertently encourage further illegal trade.
