Humbe tenuicornis (Schaum, 1853)

Caveat to the new random selection of featured creatures - if all photographs of the randomly selected subject (Morphacris fasciata) are blurry, selecting a neighbouring species is acceptable.

And so I give you:

Although I like this angle, I recognise that it's a little generic, so I'll be generous and give you another shot of this species:

Both images captured in Chongwe, Lusaka, Zambia in February 2013, using Olympus DSLR with 40-150mm Zuiko Lens and 3 KOOD magnifiers.

This lovely grasshopper is:

Humbe tenuicornis

(Schaum, 1853)

Although widespread and fairly awesome, it's the only species in the genus. Which adds a level of confidence to my identification of this (African) species. 

I can't say much about it, except that it seems most common late in the rainy season and, like all known true grasshoppers, is probably primarily herbivorous. It has no common name that I'm aware of, although, as children, my sister and I referred to this (and several less abundant species) as 'dinosaur grasshoppers' because of the inflated, keeled pronotum, which was vaguely reminiscent of the hoods of Ceratopsids such as Triceratops. I did say vaguely.

As always, the Orthoptera Species File is the place to go to identify tropical orthopterans. It's strongest in the US and Europe, for which purpose-built guides can be found, but African grasshoppers are generally well covered, as are most katydids (other family groups are not as complete for their coverage of images and ranges). 

 

Lobosceliana loboscelis (Schaum, 1853)

I have, to my unending surprise, met people who intensely dislike grasshoppers.

Female, sitting on my index finger, Chongwe, Lusaka, Zambia, October 2011. Taken using an Olympus E-420, Zuiko  40-150mm lens and two (possibly three) KOOD magnifiers.

This lovely species, which, as an aside, doesn't ever form the large, mobile locust swarms that arise when grasshoppers are subjected to poor land management practices (read - people who farm with machines when unemployment is at record levels). They're primarily a species of leaf-litter, which means that they're not great at surviving in developed areas, but at the edge of the suburbs, they can just about cling on.

And to give you a short break after all that text, here's the male:

Lobosceliana loboscelis male in August 2011, in Chongwe, Lusaka, Zambia. Photograph taken using Olympus E-420 DSLR, Zuiko  40-150mm lens and 2 KOOD magnifiers.

This is one of a number of well-camouflaged grasshoppers in the family Pamphagidae, some of which are referred to as rock-grasshoppers or similar, based on their often incredible camouflage. Of the central African genera, Lobosceliana is quite distinctive, being considerably less thorny than most of its relatives. Within Lobosceliana, L. loboscelis  wingless females can be identified by, among other things, the peculiarly deep, curved keel to their hind femora.

And that's all, folks!


UPDATE: After a more recent (January 2014) encounter with a female L. loboscelis, I can now report of an interesting defensive display: at night, when resting, they puff air out of their abdomen and periodically violently kick out their legs if touched, thereby giving a fair impression of a disgruntled puff adder (an impression that is rather detracted from if a torch is close at hand). Enough to make my blood pound before I saw what it was, at any rate.
