So weird. I read your post yesterday and then had a similar experience last night. I got a female bee and lesser a couple weeks ago. The lesser fed on the first try and my normal boy has never missed a meal, but the bee would not eat. At first I thought it was because she was still settling in or because I was trying to switch from live to f/t, but last week I thought I noticed her belly a little pink so I thought maybe she was going into shed. Tried feeding again on Sunday, and she refused again. Checked her out and couldn't see any sign of shed in her eyes, didn't look the least bit cloudy to me. I decided to try feeding live just to get her to start eating. She took it right away. When I came back to check on her she had started her shed. Each one really is unique. My male displays all the classic signs when he goes into shed, but it looks like my new arrivals might be a little harder.
