So I'm thinking of making the switch to mealworms as my main feeder for the obvious convenience factors of keeping/maintaining them over crickets. Mealworms seems to be a very popular choice among the members of this forum. I am currently feeding my gecko 10 mealworms every other day. I will have to throw in the odd cricket or so every once in a while to vary the diet and also partly out of necessity as the calcium and vitamin supplements do not stick well to the exoskeletons of the mealworms. Although mealworms are popular on this forum, there are members of other gecko and reptile forums on the web who seem to be strongly against using them as a main feeder based on the reasoning that the hard exoskeleton can cause impaction and that they are poor in nutrition. Has anyone ever had this issue with mealworms? There is an interesting article by Dr. Danny Brown, "The Pros and Cons of Mealworms as a Food for Reptiles", which you can easily google. Although it does raise some points to consider, I am a bit skeptical on some of the findings as there is no explanation on how he obtained the data or came to some of the conclusions.
