Peucetia viridans
Green Lynx Spider: Advanced Care Guide
Keeper Snapshot: A bright green, fast-jumping ambush spider that lives up on plants. Give it vertical twigs and foliage, light misting that dries fast, strong airflow and tiny prey.

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
- Small juveniles: tiny secure vial or Baby Buddy, mist one wall only
- Larger juveniles and adults: vertical Bark Buddy setup with twig and foliage perches
Warnings First
- Very fast jumper and an escape risk, especially tiny juveniles. Keep vials and lids secure.
- Tiny spiderlings drown in almost nothing. Use misted droplets, or a cap packed with grit, never open water.
- A constantly wet perch is how these are lost. Let foliage dry within hours and vent low on one wall, high on the other.
- Premolt: it stops eating and sits tight. Remove uneaten prey and leave it alone until the new exoskeleton hardens.
- Never offer oversized prey. Feed small flying or soft-bodied insects.
- Keep ventilation strong to prevent mold, and skip dense hiding clutter where prey rots.
Simple Care
- Give it twigs and foliage, not an empty cup.
- Vent low on one wall and high on the opposite wall so air rises past the foliage.
- Mist lightly for drinking droplets and let the foliage dry within a few hours.
- Skip open water. If you use a cap, pack it with grit.
- Feed small flying or soft-bodied prey about weekly.
- Keep small juveniles in tiny secure vials where they can find prey.
- Watch, don't handle. It is a very fast jumper.
Advanced Keeper Notes
Enclosure & Microclimate
- It hunts by sight from perches. Give vertical structure and plant-like anchor points, and use clutter for perches, not dense hiding where prey rots.
- Run airflow vertically: in low, up past the twigs and leaves, out high. Lid-only vents leave damp air around the perch where the spider sits.
- Water comes as droplets, not humidity. Mist lightly, let the foliage dry fully, and let the vents flow.
- Judge by touch: leaves and twigs dry within a few hours of misting, with no condensation on the walls.
- For juveniles in vials, mist one wall, not the whole vial. The spider drinks from the wall, the foliage stays dry and the tiny air space doesn't stay soaked.
Feeding, Growth & Maintenance
- Offer small flying or soft-bodied prey about weekly. Never oversized prey.
- Feed to abdomen condition rather than a fixed schedule, and don't overfeed.
- Premolt: it stops eating, dulls in color and sits tight. That's normal. Remove uneaten prey, leave it alone, and wait a few days after the molt before feeding.
Possible Origin / Range
- Likely native range: Southern United States, Mexico and Central America, up in vegetation.
- Habitat translation: Plant life becomes a tall, ventilated enclosure with plant-like perches, light misting for drinking droplets, and foliage that dries between mistings.
Advanced Keeper Details
- A visual ambush hunter that relies on sight, climbing and perches.
- Move larger juveniles up to a vertical bark setup once they are big enough to display.
- A permanently wet ambush perch is how these are lost, so airflow is the main setting to get right.
