Sorry about the quality...my camera was not co-operating and the glare from the glass made it a bit difficult.
Originally I saw this and wasn't sure if it was bug sex or if one was eating the other
This is upon closer inspection...
A few minutes later I looked again (after throwing out (and up) my food, and this was happening
At this point I realised that cockroaches shed their exoskeleton. I had no idea because they creep me out so I try to stay away from them as much as possible. I was fascinated yet grossed out at the same time. I can handle bugs and such, but roaches give me the heebies. Shortly after I took this photo, the cockroach disappeared. I looked everywhere for it and didn't find him until 30 minutes later.
You can see he went from white to a brownish colour. S/he also squished back down to normal cockroach size/shape (well normal for Australia...we just don't grow roaches like this in Canada). I was so grossed out, but very fascinated in this whole process.
