When I raise them, I give them clean, dry, bug-free soil or dry, clean, bug-free leaves to burrow under - either will do. They're an easy cat to raise, Mechelle - you'll enjoy them! I just planted some pentas in my garden the other day, and I was trying to decide if I'd rather have the blooms (which butterflies nectar on) or the tersa sphinx cats - either one's okay! Sherry

If they are in a tank you can get a reptile heat mat that you can put on the bottom of the tank (outside) so it will keep the temp up for you. I am sorry I cant answer the main question but I am sure someone will.

KC, Having written and published a specific work myself I understand the time, effort and expense involved in not only travel for research and field work, but writing, editing, etc and publication costs IF all are paid for by the author(s) themselves (more about that later). Quality color photographs are very expensive in books - the higher the quality the more expensive. Even so the prices asked for many books is ridiculous, and is all about the profit that can be made on them. I covered ALL of the expenses and did all the work for my project myself, and gave all the copies away at no cost (all 5 printings). My purpose was to record and share (which did add some limited notoriety as well), but it was not to make money on. While some of the books I refered to (and many others) are spectacular as photo albums, did require a massive effort on the part of authors if they did the field work themselves, and may contain enough technical information to help offset their cost, they are still overpriced IMO. That later part... most are written by authors with institutional backing where most if not all expenses are covered by their backer. Brings to mind when I was picked for a special team to go do lepidopteran field work in China for a couple of months in the 90's, and couldn't go because I did not have those ties and could not justify the expenses out of pocket when I still had a son to put through college starting in a couple of years. Unfortunately some of the early works and discoveries have been lost in later references, but they still hold water and so still have value. Dozens of my research papers, books and other references are as old as the hills, but I'd rather refer to them than a lot of the stuff being published today that is often just copied work that was only done for the notoriety, the almighty buck or to record it (with notoriety as a by product). Teaching from a reference by a staff member is nothing new, still goes on today. A nemisis of what is supposedly called higher education. It's not right, but it still prevails. Larry

The first one is Regal Moth, Citheronia regalis . http://edis.ifas.ufl.edu/in209 The last caterpillar is the dreaded green hornworm . Hornworms are green caterpillars with white diagonal markings on their sides. The tomato hornworm larva has eight L-shaped stripes, each hooking backward, while the tobacco hornworm has seven oblique stripes that do not turn backward. The tomato hornworm usually has a black "horn" at the rear while the tobacco hornworm has a red horn. The horn is prominent from the time the larva hatches from the egg. Hornworms reach a length of 3" to 4" in three to four weeks. They are voracious feeders on tomatoes, tobacco, eggplants, peppers and weeds of the nightshade family. This should state they are voracious eaters of anything they can get !! Highly destructive . http://edis.ifas.ufl.edu/in158 Here is a link that might be useful: Hornworm
