Moss-mimicking mantid

November 13, 2013 • 5:56 am

A tw**t from The Featured Creature led me to a description of this mantid on their home page.

It may be Pogonogaster tristani, described in 1918, but information about it is very thin; there’s not even a type locality given in the Mantodea Species File, but it’s from the Neotropics.The FC website describes it, and how it was spotted and filmed only a month ago (the site also has more photos):

Back in 2012, photographer Oscar Blanco was lucky enough to spot this minute praying mantis that mimicked its mossy environment to perfection. Its abdomen is covered in leafy appendages that make it appear to be half plant, half insect. He snapped a few quick shots of it and then moved on. Little did he know, this was a species only known from a single text dating back to 1935.

Blanco met with an expert on mantises who traced the description of the little moss mantis back to the 1935 text by Rehn, which described a species very similar to it. However, there were no photographs or illustrations available so the species name is, currently, just an educated guess. Blanco and the expert decided that it might in fact be the elusive Pogonogaster tristani.

The mantis was not spotted again until October 6th, 2013 thanks to Blanco’s friend with hawk-like eyes who spotted another tiny specimen. The photo below shows (what they believe to be) a nymph of the species, though the adult probably does not get to be much bigger.

The color is perfect.

It’s very small, but clearly cryptic, and I think the hypothesis of moss mimicry is correct.

And there’s a video, too:

When Blanco had the fortune of coming across the rare creature for a second time, he jumped on the chance to film it. Here we have (what might be) the only video footage of this spectacular mantis:

Be sure to visit Blanco’s website, MicroMacroPhoto, which has lovely pictures of insects and arachnids. His jumping spider pics are terrific, and we all love that kind of spider, don’t we?

UPDATE: Reader Lou Jost, a biologist working in Ecuador, saw this post and sent three pictures of a mantid taken in one of his study sites. There was also a note:

That moss mantid you posted looks much like this thing our reserve caretakers found and photographed in our Rio Zunac Reserve in eastern Ecuador. (Photo: Recalde/EcoMinga) But our thing seems not to be a mantis. And it is huge, not tiny.  Beautiful convergence.

    1. Agreed. I was about to post the same thing. Both are very cool.

      I found a deceased lichen-colored mantis once in Florida, and gave it to another instructor. I should have either kept the specimen or at least taken a picture. I’ll see if I can find another specimen in the springtime.

  1. It’s surprising how tiny the little moss mantis is since I’m so used to our much larger ones.

    We all do like jumping spiders but if they were much bigger, some of us would be terrified.

  2. The original description of Pogonogaster tristrani is available online here at BHL. The type is a female, collected somewhere in Costa Rica, 1600 m asl. It’s length is 25.5 mm.
    There are also illustrations of the abdomen with its characteristic appendages, the head and the front legs (plates XVIII and XX at the end of the volume).
    That should help with identification.

  3. You have to love the colour names in that description (see link from Raimas above): antimony yellow … dull buckthorn brown … washed with ferruginous … weak and pale turtle green … fuscous tipped … dull mummy brown … dresden brown.

    1. These colours are presumably named on a pre-Munsell reference card, which ought to be specified in the methods section of the paper (and maybe it is, I’m download-limited at the moment).
