I agree. At least 2 days after feeding. I made the mistake of puting my pied male in with my bumblebee female the next morning after feeding. I guess she got stressed and she regurged. I pulled her from breeding until next season because of it . A lesson learned that i will never repeat
Things happen and this is how we learn the proper way to breed\keep these animals. Trail an error. I bred 4 girls last year and didnt get anything so dont worry crummy things happen to everyone in this community
