Mascara Giant Birdeater

## Overview A striking large terrestrial species introduced to the US hobby around 2019. Distinguished by high-contrast black femurs with a rose/red 'mascara' blush coloration behind the eyes and on the carapace. One of the few Pamphobeteus species where males are more colorful than females. Males develop deep purple coloration with pink highlights, while females mature to darker brown with black accents. Juveniles display a prominent 'Christmas tree' marking on the abdomen that persists into adulthood.

## Husbandry

### Temperature Ideal: 78°F Range: 70-85°F Tolerates a wide temperature range. Warmer temperatures increase feeding response, growth rate, and molt frequency. Native to lowland dry forests in Ecuador where temperatures are relatively stable.

### Humidity Range: 60-80% More adaptable than most Pamphobeteus species. Can be kept on dry substrate as adults after being raised on moist substrate as slings. Unlike most other Pamphobeteus that need consistent moisture, this species tolerates longer dry periods. Slings under 3 inches should be kept on slightly moist substrate.

### Substrate Type: Coconut fiber, peat moss, or ABG mix. Topsoil without fertilizers also acceptable. Depth: 4-6 inches for adults, 2-3 inches for slings

### Feeding Prey: Crickets, Dubia roaches, Red runner roaches, Superworms, Occasional pinky mice for large adults Juvenile: 2-3 times per week Adult: Once per week to every 10 days

## Behavior Temperament: Calm Activity Level: Moderate

Not the skittiest Pamphobeteus species. Often visible with face in burrow and abdomen exposed - good display species. Can handle enclosure being moved carefully without bolting. More bold than skittish but not aggressive. Will kick urticating hairs if persistently disturbed. Males tend to be more reclusive ('pet holes') than females.

## Special Considerations

### Sexual Dimorphism Unusual among tarantulas - males are more colorful than females. Males develop deep purple with pink highlights on carapace and legs with jet black abdomen. Females mature to darker brown/black. This reversal of typical dimorphism makes the species popular for those wanting colorful adult males.

### Humidity Adaptability Unlike most Pamphobeteus species that require consistent moisture, P. sp. 'Mascara' is notably adaptable and can thrive on dry substrate as adults. This makes them more forgiving of husbandry mistakes than related species.

### Hobby Status Relatively new to the US hobby (introduced ~2019). Still technically undescribed (hence 'sp.' designation). Similar in appearance to P. sp. 'Platyomma' but distinguished by higher contrast coloration and the mascara-like marking behind eyes.

### Breeding Sac Management Documented breeding attempts show females may eat sacs unexpectedly. One breeder lost a sac the day before planned extraction. Recommend pulling at 30-40 days rather than waiting full 8 weeks. Elevated temperatures (top shelf placement) may aid sac development.
