Difficult to see what is going on there Charles. Would the red thing be the parasite? What is the lighter coloured thing it seems to be on, which curves around it somewhat? Is that part of the spider? Wouldn't have thought so, it looks like something on the spider rather than part of it. Or part of the parasite perhaps? Or is it the parasite? In which case what is the red blob on top of it? Intriguing puzzle. Can't make it out.
