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.

Enclosure Format / Size Class
- vertical bark setup for larger juveniles/adults
Warnings First
- Very fast jumper
- Tiny escape risk
- Avoid oversized prey
- An ambush hunter that lives up on foliage needs the foliage to dry between mistings. Vent low on one wall and higher on the opposite wall so air rises past the plants.
Simple Care
- Use twigs/foliage, not an empty cup.
- Vents low on one wall and higher on the opposite wall so air rises past the foliage and dries it back.
- Mist lightly for drinking droplets.
- If you use a water dish rather than droplets, pack it with grit: a tiny lynx spiderling drowns in almost nothing.
- Feed small prey.
Advanced Keeper Notes
Enclosure & Microclimate
- Green lynx spiders rely on vision, climbing, and ambush positions. Provide vertical structure and plant-like anchor points.
- Small juveniles do best in tiny secure vials where they can locate prey.
- Because this species lives up on the foliage rather than on the ground, run the airflow vertically: vents low on one wall and higher on the opposite wall so air enters at substrate level, rises past the twigs and leaves, and exits above. That is what dries the foliage back between mistings. Lid-only venting leaves damp air sitting around the plant structure where the spider actually sits, and a permanently wet ambush perch is how these are lost.
- Ventilation and humidity are one setting here, and the moisture is delivered as droplets rather than as ambient. Mist lightly for drinking, let the foliage dry fully, and let the vents flow. There is no humidity number to hold.
- Judge by touching the foliage rather than by a gauge. Leaves and twigs should be dry within a few hours of misting, and there should be no condensation on the walls of the vial or enclosure.
- If you offer standing water instead of droplets, use a cap packed with grit so there is no open surface. A juvenile lynx spider is small enough to drown in a droplet-sized pool, which is part of why droplet misting is the usual approach for this species.
- On juveniles in vials, mist one wall rather than the whole vial. The spider drinks from the wall, the foliage stays dry, and the tiny air volume does not stay saturated.
Feeding, Growth & Maintenance
- Light misting provides drinking droplets, but keep ventilation strong to prevent mold.
- vertical bark setup is a natural upgrade when they are large enough to display.
- Molting: a premolt spider stops eating, dulls in color, and sits tight in its retreat or web. That's normal. Remove uneaten prey, don't disturb it, and wait a few days after the molt (until the new exoskeleton hardens) before feeding.
Possible Origin / Range
- Likely native range: Southern United States, Mexico, and Central America vegetation habitats.
- Habitat translation: Tall ventilated enclosure with plant-like perches and light misting access.
Advanced Keeper Details
- This is a visual ambush spider; clutter should create perches, not dense hiding where prey rots.
- Avoid overfeeding; abdomen condition tells you more than a fixed schedule.
