🍂Afghan Leopard Gecko
Autumn: Maintain feeding to build tail fat reserves ahead of winter; 2–3 times per week.
Black Soldier Fly Larvae
Autumn: Harvest remaining larvae. Colony activity decreases with shorter days.
Hornworms
Autumn: Maintain cultures at room temperature. Continue commercial diet only.
Henkel's Leaf-tailed Gecko
Spring: Increase feeding as temperatures warm; offer appropriately sized insects 3–4 times per week, dusted with calcium.
Sorah Leaf-tailed Gecko
Spring: Increase feeding as humidity rises; offer small insects 3–4 times per week with calcium dusting.

Recommended Tank Sizes
Enclosure size guidance by life stage for Desert Night Lizard. General guidelines — always research species-specific requirements and size up whenever possible.
10–20 gal (38–76 L), 20"–30" long (51–76 cm)
30–40 gal (114–151 L), 36" × 18" (91 × 46 cm)
40–50 gal (151–189 L), 36"–48" × 18" (91–122 × 46 cm)
50–75 gal (189–284 L), 48" × 18"–24" (122 × 46–61 cm)
Ferguson Zone & UVB
The Ferguson Zone system categorizes reptiles by their natural UVB exposure needs, guiding lighting choices.
Temperate species benefit from low-to-moderate UVB (5–6% T5). They bask intermittently and seek cover in foliage and leaf litter. Provide a gradient with both light and shaded zones.
Zone 1
Crepuscular / Shade
Zone 2
Occasional Basker
Zone 3
Open Sun Basker
Zone 4
Full Sun Lover
Temperature Gradient
basking surface
85–90°F (29–32°C)
warm ambient
75–82°F (24–28°C)
cool side
68–75°F (20–24°C)
Humidity
40–60%
Lighting & Photoperiod
5–6% T5 HO UVB bulb. Halogen or incandescent basking bulb. 12 hr photoperiod in summer, 8–10 hr in winter to simulate seasonal changes.
Heating
Overhead basking bulb. Ceramic heat emitter or heat mat for supplemental warmth if ambient drops too low, especially for tropical temperate species.
Decor & Furnishings
- •Cork bark hides and logs
- •Live or artificial plants (Spider Plant, Ferns)
- •Leaf litter (oak, maple) for natural cover
- •Rocks for basking and structure
- •Shallow water dish
Setup Notes
Some temperate species benefit from a brumation (cooling) period in winter — research species-specific needs. Maintain moderate humidity with occasional misting. Leaf litter enriches bioactive setups.
