WC and Roaches
I rescued an adult WC Melleri about a month ago. It had been in the States for about a month. It had been only given crickets during that time. I started putting an adult male roach in the feeding bucket along with four or five adult crickets. The Melleri would eat all the crickets quick, and then would look at the roach for a long time, then move away. Later in the day, I think when the Melleri became hungry, it would return to the bucket and look at the roach for awhile, then a test shot, then a strike. I do not know if it is the size, or that if looks, well, like a roach, but it was not the first thing to eat in this Melleri's list of things to eat.
One month later, the same pattern. This Melleri will eat adult male roaches when the crickets are gone. No longer does a test shot, I think to make it move around more. When it strikes a cricket, sometimes she (we think it is a female) will hold it in her mouth for a time before chewing it. Not so with the roaches. Strike, chomp, chew quickly, head slightly up, swallow.
I hope she will keep eating them, as roaches are so easy to keep and grow.
