Insect: Grasshoppers and locusts

Saw this grasshopper in Kruger. Needed a strong telelens for this photo. Does anyone have any idea what species this is, or alternatively where to find an expert who is knowledgeable in this field?

Watching the slow flow of the river. A continues movement of water down towards the ocean. Like blood flowing through a vein, keeping the body alive.

I have seen the locust on the first posting before, but I am not sure of its name. It might be a "toad grashopper" but I am unsure. I wil have a look ...

As for the locust on the second post: It is what is known as a "Bush Locust" which is a general name for a specific family of locusts (including Phymateus leprosus / Phymateus baccatus). Some members of the family are poisonous, and advertise this through bright colouring on their bodies. The family is also un-able to produce sounds because they lack the "file and scraper" apparatus of other grashoppers. The Bush Locusts is known to damage crops.

Let's wait with posting new ones till the first question has been answered, otherwise this will become a jumble....

#1 a Toad grasshopper? If I look here it does not seem likely to me.

Transvaal Museum wrote:The diversity of invertebrate organisms in southern Africa is higher than that of any other group of animals, but with relatively few specialists to identify such for the wider community of academic institutions, wildlife reserves and conservation officials. The scientists at the Transvaal Museum are uniquely equipped to help due to the large collections and library at our disposal.

This page on that site has a contact, and one can click through to several kinds of invertebrates.

Grasshopper

Unread postby PhilQ » Wed Nov 09, 2005 5:00 pm

I have had another look at the creature and wonder whether it does not belong to the family of Phasmids, order Phasmatodea, which include the stick and leaf insects. Most often one encounters pictures of green leaf insects, but it is a large subfamily and some sources show brown leaf insects resembling dead leafs, e.g. link
and http://photographytips.com/page.cfm/5944. Anyone further ideas?

Looking in book by Mike Picker et al (Field Guide to Insects of SA) I would suggest a type of grasshopper of family Pamphagidae. Can't find the precise one (apparently there are 71 in the region!) but it fits closest with the features shown.

Names given are toad grasshopper, stone grasshopper and so on. Typical is the odd shaped antennae, rough body, spines on legs, and the keel behind the head.

Not an expert though so might be wrong!

With expert help the riddle what species this grasshopper is has now been resolved:
The grasshopper in your photo is indeed a member of the family Pamphagidae. It is a female of the genus Lobosceliana (unfortunately, it would be impossible to tell which species of Lobosceliana based on a picture alone.)
Species of this genus are highly sexually dimorphic, and while females are completely wingless, the males have long, leathery wings, and produce very loud stridulations.

This provides me with an opportunity to point out, for those interested, a few very informative websites: http://140.247.119.145/africa/ - http://home.hccnet.nl/mp.van.veen/sprin ... _rest.html (in Dutch) - http://www.bioimages.org.uk/HTML/T365.HTM and http://osf2x.orthoptera.org/osf2.2/OSF2X2Frameset.htm

Thanks everybody for the help.

It is the "Koppie Foam Grasshopper".

It is a flightless grasshopper found over large parts of S.A. The red colouring is a warning signal to predators that it is poisonous. It extracts heart poisons from the milkweeds it feeds on, and exudes these in a foam when molested. Known to be fatal to dogs.

Hi Yolande,

Its an adult Green Milkweed Locust(phymateus viridipes)....They obviosly do eat plants, mainly that of the milkweed, where they seem to retain the poisons, and have known to be fatal if consumed...You'll notice when you handle them, they release a foam...which is where the poison is released. They won't be doing any considerable damage to the gardens.

Well thanks again Justin. My you do know a lot. :thumbs_up:
It is very interesting. They have beautifull underwing colours of blue and red. BUT I prefer watching them from ( very very) far!!!!
There are HUGE amounts in the gardens, and they seem rather clumsy when flying from tree top to tree top, and I am very sure that, if they land on me, I'd surely die on the spot!!! :big_eyes:
I am very afraid of them! When visiting the gardens last week, I was too afraid of going to the falls and stayed right at the entrance side watching the birds from there.
