The native Polistes aurifer. (golden paper wasp) frequently. overwinters in attics of homes. The queens emerge during the. first warm days of spring (as. early as March and April), select. a nest site, and build a small. paper nest in which they lay.
The length of incubation (or amount of time it takes for eggs to hatch) depends a lot on weather conditions. Temperature, humidity, rainfall, and other factors influence incubation. Generally, land turtle incubation ranges from 45-90 days (I know that's a long time to wait when you want to see baby turtles!). I suggest you start checking on the nest every couple days starting at the six week point. I wouldn't expect to see any babies until August at the earliest.
Plan for Hatchlings. While it's unlikely that all 20 to 30 eggs in a clutch of eggs will hatch, you may find yourself with a dozen or more hungry little mouths at the end of the 2- to 3-month incubation. Newly hatched turtles are the size of a quarter at hatch, and grow to about 6 inches long in their first year.
