    Hi Sean,

    This is not Spilostethus pandurus. I don’t know African insects (at all), but going by the little info I have this should most likely be Spilostethus trilineatus (Fabricius, 1794).

    I’m slowly (slowly!) gathering images for an overview of red-and-black bugs worldwide and would be interested to use your image at some point (fully credited of course). Please drop me a note :o)

    Cheers, Arp

      Hi there Arp.

      Thanks for the feedback on this bug. I always strive to make sure that what I post here on vuurvleigie.net is accurate, but alas we can’t all be 100% right all the time. I have to make do with what information I have in the books at my disposal and this is the name I came to use. I will use the email supplied to send you a copy of the image as soon as I have a chance.

      Regards

      Sean

    Hi Sean,

    Many thanks for the image and usage permission. As a reference for other visitors, my feeble ID attempt is mostly based on this PDF by Dawid H. Jacobs. More info and links can be found in my forum posts here and here.

    Thanks again!

    Cheers, Arp

      Arp,
      You are most welcome. I often see other red and black bug like these that are similar. If you want, and if I take a photo, would you like me to send them your way?

        Does a rag doll have hairy nipples? 🙂
