After a gap of about 8 years I've found an elephant hawk moth caterpillar, (2 in fact) I'm thrilled & have looked back at an old thread to remind myself how to care for them correctly & have now found some willow herb & lightly cooked & dried some leaves but I woukd like to know if they are ok together or if I should separate them. They are in a large container with plenty of room to avoid each other if they want. They do seem to be largely ignoring each other. I'm so pleased to have the opportunity of releasing this beautiful moth, next spring so I contestant to jeopardise anything. Any advise appreciated
