Brandi, I wanted to let you know what we found. To answer your earlier questions, it seemed as though we there was plenty of water they did not do much cleaning of the flesh. My guess is that they are consuming it as a source of liquid. We used carrots as a water source and it seemed to work fine. I think if they were removed a day or two in advance the mealworms would have cleaned at a higher rate. 2. We used oatmeal as a substrate. After the fact, we should have used something finer as it was hard to clean the oatmeal. We had a ton of mealworm sheds that we couldn't get out of the substrate. 3. No flesh was left behind. The skulls were clean. I had one case were a toothbrush was used to remove the periosteum, but otherwise, they were completely devoid of flesh inside and out. Since we used such small animals I'm not sure that the outcome would be the same with something bigger. However, the original citation ( Allen and Neill 1950) used larger animals with success. Also, it is interesting to note that the time needed to clean a mouse skull when there was no access to water was only about 4 hours. I haven't worked with beetles so I don't know if that's fast or slow. Once again thank you for your support, Matt

The first paper gives some idea of the need for moisture and the second some basic idea of the amount of food they will consume. I think the rest of your questions will be answered with the pilot study. Urs, K. C. D., & Hopkins, T. L. (1973). Effect of moisture on growth rate and development of two strains of Tenebrio molitor L.(Coleoptera, Tenebrionidae). Journal of Stored Products Research, 8(4), 291-297. Evans, A. C., & Goodliffe, E. R. (1939). The utilisation of food by the larva of the mealworm Tenebrio molitor L.(Coleopb.). Physiological Entomology, 14(4‐6), 57-62.

Brandi, thanks for the questions and your support. I will look into those questions. I'm pretty sure they need little water, but exactly how much I don't know. We are planning on using oatmeal as the substrate. We will be running a small pilot study to figure out the rate and the amount of tissue left on a sample. If you don't mind me asking, what field are you in? This project has brought us in contact with a huge range of people. It has been great for our younger members.

Mieke, I'm sorry we used your picture without your consent. We looked for a picture via Google and could not find a link back to the original site. I realize it's a little late, but do you mind if we use your photo for our school science project? If it is not alright I will change it today so that we are no longer using your picture. Sorry for the inconvience.
