Autumn: Maintain feeding to build tail fat reserves ahead of winter; 2–3 times per week.
Hornworms
Autumn: Maintain cultures at room temperature. Continue commercial diet only.
Mealworms & Superworms
Autumn: Continue regular feeding. Monitor for pupation and separate beetles from larvae.
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.

Incubation
Temperature, humidity, and timeline guidance for incubating Texas Horned Lizard eggs.
82–88°F (28–31°C)
60–80%
45–75 days
Incubate eggs in a sealed container with slightly moistened vermiculite or perlite (1:1 ratio by weight with water). Do not turn the eggs — keep them in the orientation they were laid. Open the container briefly once a week for air exchange.
In many desert species (e.g. Leopard Geckos), incubation temperature influences sex determination: lower temps (~80°F) produce females, higher temps (~88°F) produce males, intermediate temps produce mixed clutches.
Hatchling & Baby Care
House hatchlings individually in 10-gal tanks or kritter keepers with paper towel substrate (easy to monitor feeding and fecals). Provide a small hide on each end and a shallow water dish.
Basking surface 90°F, warm ambient 85°F, cool side 75–80°F
Feed pinhead crickets or small mealworms daily. Dust prey with calcium + D3 at every feeding and a multivitamin once a week. Food should be no larger than the space between the baby's eyes.
Do not house hatchlings together — they may nip tails or toes. Keep a moist hide available to support healthy sheds. First shed typically occurs within 3–5 days of hatching; begin offering food after the first shed.
