Around this time of the year, the lucky inhbitants of Johannesburg in South Africa are often visited by this handsome beast, known as the Parktown Prawn (Libanasidus vittatus). Originally found only in indigenous forests of northeastern part of the country, in 1960’s these cricket and katydid relatives (Anostostomatidae) started appearing in gardens and houses around Jo-burg. It is not quite certain what attracted them there, but it was likely a combination of the relatively high humidity of suburban gardens, combined with the lack of their natural predators, mongooses and monitor lizards, in this anthropogenic environment.

These beautiful insects are feared by many, but of course they are completely and utterly harmless. The massive jaws seen in the males are used only in territorial battles with other males, and cannot be used to stab or bite a person. Their only defense is, unfortuntely, rather odorous defecation. But if left alone they make a beautiful addition to the South African urban ecosystem.

    I once got stabbed in the finger by what I believe was the female ovipositor (that long spike on the back of the abdomen) while clearing leaves that had accumulated around the pool pump/filter box. I guess she liked the dark, warm environment and rotting vegetable matter. It felt like a needle puncture. I didn’t seem to suffer any inflammation or infection and the pain was only momentary. It did freak me out though as I had always regarded these guys as pretty harmless.

    Prawn said in a Sarth Ifrican accent now immediately brings to mind the rather good Sci Fi film ‘District 9’. It’s used a derogatory term for the (sort of insect-like) alien slum dwellers.

    1. Duncan, believe it or not, but my photos were actually used to help design the aliens in “District 9.” You can read about here:

        Very cool, Piotr! Surely there aren’t many entomologists who can claim such a thing…

        Also, just wanted to say that I bought your book ‘Relics’ as an early xmas present to myself, and it’s absolutely fantastic (I couldn’t bring myself to hide it away until the 25th)… I was recommending it to Kevin Judge (at Grant MacEwan University) the other day, as he works on sagebrush crickets, so you can send me the royalties from future sales via paypal ;)

        You’ve gone up in my estimation even more! By the way, I hope you enjoy posting these pics because my daughter Cara (7) and I (>7) think they’re incredible.

  3. With a common name of …prawns, does anyone eat them, or is that just a vague resemblance type of thing?

    These animals are really beautiful, and your photographs show their amazing structure and colors very well. Anostostomatidae are one of my major groups of interest. In a few weeks I will be going to New Zealand to study ground weta, but I hope to get a chance to see some tusked weta.

    1. Isn’t it funny how the same animal can have a very different reputation in different places? In New Zealand anostostomatids are the subject of national pride and intensive conservation efforts, whereas in S. Africa most people are only concerned with how to get rid of them.

  5. Nice photos.
    I grew up with these guys in Jo-burg and used to love playing with them in the garden (I still have a Parktown prawn T-shirt). However most of my memories of these little critters are of my relatives telling me how hard they were to squash beneath their foot! Quite sad really.
    Cheers
