I am breeding for the first time this year and recently paired up a female fire (about 1900 grams) with a firefly male and noticed that there is some smeared blood showing up after they have finished. This is the second time I have seen it when they are paired but I can't find any wounds on either of them to explain it. Any ideas what might be going on? I included a photo that shows a couple of the spots but there are more and they are more red than they appear in the photo.
