Canopy jumping spider care guide
Phidippus otiosus
Vertical space and clutter. Jumpers hunt by sight and sleep in a silk hammock near the ceiling, so the enclosure needs height, hard points to web to, and a front door so you don't tear the hammock every time you open it.
Arboreal — vertical height first
Canopy jumping spider enclosure size
Arboreal — vertical height first. An adult canopy jumping spider should live in at least 4" L × 4" W × 8" H; we build toward 6" L × 6" W × 12" H (0.5 × 0.5 × 1 ft, roughly 0.3 sq ft of floor and about a 2-gallon glass equivalent).
One spider per enclosure — jumpers are cannibalistic outside a supervised pairing.
- Spiderling / sling
- 3" L × 3" W × 4" H recommended · min 2" L × 2" W × 3" H
- Juvenile
- 4" L × 4" W × 6" H recommended · min 3" L × 3" W × 5" H
- Adult
- 6" L × 6" W × 12" H recommended · min 4" L × 4" W × 8" H
Temperature and heating
Heat the room, not the enclosure. If the room drops below 68 °F use a thermostatted space heater or a heat mat on the outside of a side wall (never under the substrate) — heat mats under a burrow cook the animal.
- Basking / warm surface
- None — no basking site, no heat lamp
- Warm side (ambient)
- 72–80 °F ambient room temperature
- Cool side (ambient)
- 70–75 °F ambient room temperature
- Night
- Room temperature; a 5–8 °F night drop is fine
Lighting and UVB
UVB: None — invertebrates need no UVB and bright light stresses them. Run lights on a Ambient room light on a normal day/night cycle; keep the enclosure out of direct sun photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 60–70% ambient. Dampen one corner of the substrate every week or two and keep a water dish full — never soak the whole enclosure.
Substrate and depth
Coco fibre or paper towel (easier to spot escaped feeders). Depth: 0.5–1 in — they never burrow.
- Ventilation: Mesh or drilled vents on two sides. Jumpers tolerate dry air far better than a wet, still enclosure.
Enclosure tips and furnishing
- Branches, silk plants and cork at the top third for hammock anchors
- Angled sticks so the spider can stalk downward
- Cotton-plugged water vial or a light daily mist on one wall
Build list
- Front-opening vertical jumper enclosure (6 x 6 x 12 in) — Top access destroys the hammock; a magnetic front door leaves it intact.
- Flightless fruit fly culture — Hydei for adults, melanogaster for juveniles — the whole diet in one feeder.
- Digital thermometer / hygrometer — Inverts are kept at room temperature — you need to know what the room actually does, not guess.
- Long feeding tongs and a catch cup — Every interaction — feeding, water top-ups, rehousing — should happen without your hand near the animal.
Canopy jumping spider FAQ
How big should an adult Canopy jumping spider enclosure be?
At least 4" L × 4" W × 8" H, and we recommend building to 6" L × 6" W × 12" H — about 0.5 × 0.5 × 1 ft, or a 2-gallon glass equivalent. Arboreal — vertical height first.
What temperatures does a Canopy jumping spider need?
Basking or warm surface None — no basking site, no heat lamp, warm side 72–80 °F ambient room temperature, cool side 70–75 °F ambient room temperature, night Room temperature; a 5–8 °F night drop is fine. Heat the room, not the enclosure. If the room drops below 68 °F use a thermostatted space heater or a heat mat on the outside of a side wall (never under the substrate) — heat mats under a burrow cook the animal.
Does a Canopy jumping spider need UVB?
None — invertebrates need no UVB and bright light stresses them. Photoperiod: Ambient room light on a normal day/night cycle; keep the enclosure out of direct sun.
What humidity does a Canopy jumping spider need?
60–70% ambient. Dampen one corner of the substrate every week or two and keep a water dish full — never soak the whole enclosure.
What substrate is best for a Canopy jumping spider?
Coco fibre or paper towel (easier to spot escaped feeders), at a depth of 0.5–1 in — they never burrow.
How big does a Canopy jumping spider enclosure need to be for a hatchling?
Spiderling / sling: 3" L × 3" W × 4" H recommended, minimum 2" L × 2" W × 3" H. Scale up to the adult footprint as the animal grows.
How much ventilation does a Canopy jumping spider enclosure need?
Mesh or drilled vents on two sides. Jumpers tolerate dry air far better than a wet, still enclosure.
