Neojulodis vittipennis (Fåhraeus in Boheman, 1851)

A jewel beetle. Wondering about the name? Well, here's why:

Photographed in New Kasama, Lusaka, Zambia, in March 2013, using an Olympus E-420 DSLR with a 40-150mm Zuiko lens and 3 KOOD magnifiers.

Based on the distinctive patterns of most large jewel-beetles extending into this rather poorly documented group, this beautiful creature is;

Neojulodis vittipennis
(Fåhraeus in Boheman, 1851)

 For context, here's another angle:

Same individual, same place, this time on my finger for scale.

 This harmless - although, as with anything colourful, I wouldn't recommend having it for lunch - herbivore seemed content to sit in the sun and occasionally nibble ineffectually at a plant which, I have to confess, I failed to record. 

As an additional, it is worth noting that the primary reason these are jewel beetles is not because most of them are quite colourful, but rather because several inordinately colourful species have been overcollected since prehistoric times as a staple of Oriental beetle jewellery. Insect art still goes on today, although with our improved understanding of population dynamics (just because insects lay hundreds of eggs doesn't mean that there are adult insects to spare), many popular projects - such as Jennifer Angus stunning geometric mosaics (here) not only state amongst their aims the improvement of public awareness of insects, but also promote sustainable harvesting of insect populations. 

I have to say that, admirable aims or not, killing any animal for art can only seem ghoulish to me.

And that is all, folks.




nothing I have found is consistently reliable across African beetle groups, the Coleopterists society's site The World of Jewel Beetles is a good place to start for the Buprestidae. 
 

 

Burhinus vermiculatus (Cabanis, 1868)

Another vertebrate - and quite a small image:

 This rather cynical looking bird is the Water Dikkop (or, for purist Anglophones, Water Thick-Knee),

Burhinus vermiculatus
(Cabanis, 1868)

 It seems worthy of note that the Afrikaans Dikkop does not mean thick-knee, but thick-head. Something else that's been lost in translation.

Crambus pascuella (Linnaeus, 1758)

We've been having a photo-tour of Lusaka lately, so here's one from the UK to keep things from getting biased:

Crambus pascuella, Bosham, West Sussex, UK

This lovely little grass-moth is called
Crambus pascuella 
(Linnaeus, 1758)

It's one of quite a few very similar species, so I would advise you to take this identification with caution.

Anyhow, on with the show:

To give an explanation of the common name of 'Grass moth', applied to numerous related species: most Crambus and their relatives are usually seen in grassland, they sleep head down on grass, and as caterpillars they feed primarily on... yes, grassland. They can be quite lovely to behold in uncultured meadows, where a walk through the grass will send clouds of quite literally hundreds of these beautiful little moths spinning into the air and settling a few feet further on.


And that's all, folks!






An excellent (f)re(e)source for identifying British moths is UKMoths, with almost complete coverage of resident species, both native and introduced, and fair coverage of occasional migrants as well. 

Lobosceliana loboscelis (Schaum, 1853)

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

Lobosceliana loboscelis, Chongwe, Lusaka, Zambia
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. 

Synchiropus splendidus (Herre, 1927)

I've been avoiding posting images of captives specimens - the only other, to date, is the Emerald dove Chalcophaps indica, quite a while ago now. However, in the interest of taxonomic completeness, it seems necessary that I include a member of the largest class of vertebrates sooner or later, and thus far, my above-water images of free-roaming members of this group have not done well.

So, without further pre-amble:


Synchiropus splendidus, Captive Specimen.
In a private aquarium, 2010.
This is the Mandarin Dragonet,

Synchiropus splendidus
(Herre, 1927)


I shall not be going into the ethics of keeping wild-caught fish in aquaria in this post; suffice to say that, until such time that I am confident that I can provide a suitable environment in which any particular species could breed, I will not be keeping wild-caught fish.

Anyway, moving on swiftly from the shame of my past mistakes, and onto the taxonomy:

This stunning little fish, in the wild and in captivity, spends much of its time scooting along the faces of the reefs it makes its home, looking for small crustaceans and worms to eat. As you may expect, its bright colours advertise a foul taste and fairly toxic flesh, so it has relatively few natural predators. Unfortunately, as previously alluded to, its bright colours also make it highly appealing to aquarists who - due to its rather specific native diet, have a poor track record in feeding it, and it is quite common for imported specimens to die within the year, although exceptions (such as that above, which was purchased at adult size and lived six years in a small tank) do exist. Many aquarists then assume that, like the distantly related gobies, dragonets are ephemeral creatures, and replace them, leading to unsustainable pressure on wild populations.

There is a side-note of interest to the Mandarin's tale of woe: in Florida, one commercial hatchery now has, and continues to, breed this fish for sale. While this doesn't quite escape the ethics of keeping a finicky eater in a small tank where it may well - and still often does - starve, it should significantly reduce pressure on wild (Indo-Pacific) populations of these beautiful fish. 

So all in all, this tendency to get caught up ethics is why I don't like posting images of captive animals. 


That's all, folks. 



Not so much an identification aid, but for any budding marine aquarists reading this, it's always a good idea to know something about a species before you purchase it. While you can do as I did, and ask the shop-keepers and be given an uninformed and often downright untruthful answer, a good place to look up information is WetWebMedia, which not only includes fact-sheets on all the groups of fish likely to be encountered in a private aquarium, but also has FAQ pages sorted by groups of fish, where you can read accounts of what can go wrong with your fish, and decide whether you can actually prepare for such eventualities.
