Phormictopus auratus spiderling • 1″ (Cuban bronze tarantula)

Description

Described in 2005, Phormictopus auratus, commonly known as the Cuban bronze tarantula, was found in 3 provinces in central-eastern Cuba. Specimens were found under rocks and stones in forested areas, but also in soil crevices, tree trunks, caves, disturbed areas and even in a marsh mangrove [1]. These locations define P. auratus as an opportunistic burrower.

P. auratus spiderlings are brown. Interestingly, on the neighboring island of Hispaniola, Phormictopus spp. spiderlings are blue. Named for the gold highlights on its carapace and legs, P. auratus is large and robust. Females can live on the order of 15-20 years in captivity.

Spiderlings in general do better with some humidity. Therefore we suggest housing your P. auratus spiderling on slightly dampened substrate (1 part water mixed with 1 part dry substrate) and limit ventilation enough for humidity to accumulate. Room temperature (68-72F) is fine. With each molt, P. auratus acquires more drought tolerance. By the juvenile stage, drier substrate and less humidity is preferable. A water dish may help avert accidental dehydration.

Care highlights:

• slightly dampened substrate for spiderings
• elevated humidity +/- water dish support
• room temperature (68-72F) up to 80F
• less enclosure moisture for juveniles & older specimens
• an opportunistic burrower, consider a hide
• consider forest litter and plantings for enrichment
