I love roachcrossing, when I first got into the hobby I got most of my colonies from Kyle actually. His selection and customer service is amazing! Here are some pictures of those hybrids. There is a lot of variation in the colony when it comes to size and color. There are some very light adults and some very dark ones. I have separated out some of the light ones before to see if it was just a molting issue where they hadn't hardened up enough yet, but nope, they stay light. Some of the nymphs are black and some look dubia color also. Some of my adults are the size of an A. tesselata, and some are not much bigger than an E. posticus.
