Phrynus maesi
Central American Whipspider: Advanced Care Guide
Keeper Snapshot: Prioritize secure climbing surfaces and open space beneath them for molting. Keep a lightly damp base with ventilation, offer small manageable prey, and use container transfers. Big Z's recommends separate housing.
Group: Spiders & Other InvertsDifficulty: Spice 3: IntermediateSetup: Vertical and overhead cork with clear hanging-molt space, damp substrate and ventilationHandling: Catch-cup transfers only. Coax the animal into a container without grabbing its legs or pedipalps; support the cork securely if moving it with the animal.
Use This Guide Safely
- Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
- Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
- Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.
Quick Snapshot
| Temperature | Keep the enclosure in steady indoor conditions and measure near the occupied cork. No reliable species-specific care range has been established for P. maesi; avoid direct sun and unregulated heat rather than borrowing a precise range from another whip spider. |
|---|---|
| Humidity | No fixed humidity % target. Maintain lightly damp substrate and ventilation. Lightly wet an accessible wall or cork surface to provide drinking droplets, then let exposed surfaces dry between applications; do not soak the animal or seal the enclosure. |
| Setup Type | Vertical and overhead cork with clear hanging-molt space, damp substrate and ventilation |
| Substrate | Use moisture-holding soil or coir as a damp base beneath securely anchored cork. The priority is usable vertical and overhead grip with unobstructed hanging room; a substrate-depth number alone cannot provide a complete setup. |
| Feeding | Offer small crickets or roaches that the animal can grasp and eat comfortably. Scale portions to its body and feeding response. Remove refused prey promptly and pause feeding during a molt and while the new body is still soft. |
| Care Difficulty | Spice 3: Intermediate |
| Handling | Catch-cup transfers only. Coax the animal into a container without grabbing its legs or pedipalps; support the cork securely if moving it with the animal. |

Enclosure Format / Size Class
- Smaller animals: a secure tall enclosure with scaled cork and enough clear room to hang and molt.
- Larger animals: increase both usable climbing area and clearance; a body-length listing does not measure the full reach of the legs.
Warnings First
- A molting whip spider needs stable grip and unobstructed space below it; do not move it during a molt.
- Do not pull the animal from cork or handle it by its legs.
- Check lid and ventilation gaps carefully.
- Keep live feeders away while the animal is molting or still soft.
Simple Care
- House separately as a conservative precaution.
- Anchor textured vertical and overhead cork; keep the space beneath the molt anchor clear.
- Provide a sheltered crevice and room for the animal to extend and move.
- Keep a damp base, ventilation and accessible drinking droplets.
- Offer manageable prey and remove leftovers.
- Use container transfers; never grasp the appendages.
Advanced Keeper Notes
Enclosure & Microclimate
- The vertical-and-overhead bark design is adapted from Jordan Cadiot's Damon breeding practice and Aquazoo's whip-spider husbandry, not a measured P. maesi enclosure minimum.
- Position cork so there is both a protected retreat and open hanging room. Secure it before introducing the animal.
- Choose height and width from the animal's full reach and molt-space needs, not body length alone.
Feeding, Growth & Maintenance
- Offer prey near the climbing surface and observe without repeatedly opening the enclosure.
- Reduce portions or pause if food is refused. Remove accessible prey remains before they spoil.
- Wait for a firm body and normal movement after a molt; do not assume every animal is ready after the same number of days.
Possible Origin / Range
- Likely native range: Nicaragua is the distribution recorded for Phrynus maesi in the World Arachnida Catalog. The collection locality of these animals is unconfirmed.
- Habitat translation: This captive layout combines P. maesi keeper observations of moist substrate and slanted hides with broader whip-spider experience of vertical and overhead molting surfaces. It does not assume a particular forest locality for this stock.
Advanced Keeper Details
- Phrynus maesi and P. whitei remain distinct species, even where keepers use similar enclosure methods.
- Big Z's recommends professional advice for injury or persistent loss of condition; avoid repeated disturbance to force a closer look.
