This is a photo of a squat tub with orangetip pupae.  The side of the squat tub has full data for these pupae.  I make sure that this squat tub has intermittant high humidity during the winter; either by saturating the sand at the base of the terrarium, mist spraying or spritzing the squat tub with water, or by placing lots of snow inside the large box.  Once these pupae have been exposed to 90-150 days of cold temperatures, they can be brought in and coaxed to break hibernation and emerge.  However, desert species such as the desert orangetip, extend hibernation for up to 11 years.
