Over the past week I have been watching for the praying mantises when doing my daily check of the roses.
I have only seen one so far, but it does look bigger. I believe that the ones that I saw earlier were newly hatched nymphs.
I have done a bit of research and find that when they hatch out the nymphs eat quite a bit. Most likely it is why I am no longer seeing a lot of aphids on my roses. It is also why I am probably not seeing as many as I did the first time as they also eat their siblings.
