Thank you!Your hornworms will grow quick. Leave them at 60-65* to slow down their growth. The phoenix worms or "BSFL" can also be stored at these temps. Hornworms eat hornworm food. Repashy "Superhorn" is what I use. Not sure if BSFL will gutload on bug burger or fresh veggies but I assume they would. My cham had no interest in BSFL. To small, but your baby will love them no doubt.
