Friday mystery object #308 answer

Last week I gave you this beautiful insect to try your hand at identifying:

mystery308

From the start it was pretty clear it’s a wasp (just look at that characteristic waistline) and palreyman1414 pointed out the key things to look for in making sure it isn’t a fly pretending to be a wasp:

I believe that there are some flies that are camouflaged to look like wasps, but a close look suggests that this thingy has a full complement of four wings, instead of the two plus two halteres (?) that characterises the flies

Now there are a LOT of wasps out there – somewhere in the region of 150,000 species (more than all of the vertebrates put together) so that doesn’t narrow it down much. However, that waist isn’t just pinched-in like your average wasp, it’s petiolate (that’s science-talk for “stalked”), which means it’s one of the Sphecidae.

The large size also helps – most wasps are tiny, so big ones like this are relatively scarce, especially bright metallic green-blue jobs. This distinctive appearance brings to mind for me the Steel-blue Cricket Hunter (see below), but it’s from the wrong part of the world (and it’s more green than blue).

However, we know there are a lot of wasps, so it’s worth looking at close relatives in the Sphecidae, to see if there is anything from the right part of the world (that’s made reasonably easy by using an appropriate reference with a checklist).

It turns out that we don’t need to look too far, as the mystery specimen looks like it’s in the same genus of Cricket Hunters – Chlorion (as suggested by Ilyas) and checking out the species occurring in India has me leaning towards Chlorion lobatum (Fabricius, 1775), which is what abcdefg200 hinted at.

These active hunters don’t eat Crickets themselves, they actually get their energy from nectar, so they’re helpful pollinators. The Crickets face a more grisly fate than just being killed and eaten – they are paralysed, then buried alive with a wasp egg laid on them, which subsequently hatches and the larvae eat the still-living Cricket. Nightmare fodder.

There are a few subspecies of this particular species of wasp, but I’m not even going to try to work out which this might be, since even carrying out a proper identification to species would require time with a microscope and a lot more experience than I have with this diverse, fascinating and above all nightmarish group of insects.

As I’ve mentioned before, for the last few months I’ve been feverishly moving objects for a gallery lighting project. 

That’s pretty much done now (and looking great) so now I’m feverishly moving the Dead Zoo’s collection of over a million insects out to a new home in the National Museum of Ireland’s Collections Resource Centre.

So this week I have an insect for you to identity, which should provide a bit of a colourful change from the usual vertebrate bones:

For some of you this may be way too easy, for others, way too hard. It help to know that this was collected in India and it’s around 25-30mm long.

I hope you have fun identifying it!

Friday mystery object #307 answer

Last week I gave you this specimen from the Irish Room of the Dead Zoo to try your hand at identifying:

mystery307

Now it’s not a particularly difficult species to identify for a keen birder, so I asked for cryptic clues to the identity, and I was not disappointed. Some suggestions were so cryptic I still haven’t managed to work them out!

First in was Jennifer Mccaire who quoted a brief line of poetry:

“…Thou hast no sorrow in thy song, No winter in thy year.”

This is a section of a poem published in 1770 by John Logan – the title being “Ode to the Cuckoo“. Now, it seems likely that Scottish born Logan wrote this about the Common Cuckoo Cuculus canorus Linnaeus, 1758 that breeds in Europe and which looks like this:

Clearly it’s a different bird (one which mimics the appearance of a female Sparrowhawk) and it’s not quite the same as the mystery object – although there are similarities. However, we must keep in mind that Jennifer is of the North American persuasion, so her thoughts on Cuckoos will probably veer towards the Black-billed Cuckoo or Yellow-billed Cuckoo (or maybe the Mangrove Cuckoo, but that’s not as widespread as the other two).

If you don’t know the difference between these two North American Cuckoos, here’s a handy illustration to help differentiate:

The last few months have been particularly busy for me as I’ve been working on a lighting project in the Irish Room of the Dead Zoo in Dublin, so I’ve not had much opportunity to dig out mystery objects and get good images for you to identify.

However, I have moved pretty much every specimen in the gallery and if you want to see how much stuff that entails there’s a 3D interactive map of the space available here (if you want to have a virtual tour of the whole museum check this out). All this moving means I’ve seen a lot of specimens, so here’s one of them for you to have a go at identifying:

For a some of you this will be way too easy, so let’s have your best cryptic clues, hints and riddles as to what this is.

Have fun!

Friday mystery object #306 answer

Last week I gave you this interesting skull to identify:

Specimen LDUCZ-Z1058 from the Grant Museum of Zoology

Specimen LDUCZ-Z1058 from the Grant Museum of Zoology

I didn’t mention that top of the cranium had been removed, probably as part of a postmortem, which is quite common for zoo specimens. Of course, this made the identification a bit more tricky.

That absent skullcap led to several suggestions of Tasmanian Devil, since they do have a very similar looking facial region to this specimen, with a short and blunt muzzle, robust zygomatic arch and even the same toothcount in the upper jaw. However, the Devils have an angular process of the mandible that projects medially (towards the midline) rather than backwards in a hook, so you wouldn’t see it in a side view.

The correct answer was first tenuously suggested by palfreyman1414 in a pleasingly cryptic manner:

I’d have sworn this was a commie go-between for Cressida and Troilus

Which hints at “Red” and “Pandarus” giving us the Red Panda Ailurus fulgens F. Cuvier, 1825.

These charismatic critters are another example of an arboreal carnivore that is adapted to feed on a highly vegetarian diet, but unlike the previous mystery object (a Kinkajou) these cuddlesome floofballs eat mainly bamboo rather than fruit – rather like their very distant relative the Giant Panda (despite the similarity in diet and common name, the Red Panda is actually more closely related to the Kinkajou than it is the Giant Panda).

Red Pandas are a bit less highly specialised for feeding on bamboo than the Giant Pandas, probably because they have a more varied diet that also includes fruit, eggs, birds and small mammals. The poor nutritional quality of bamboo does mean that they spend a lot of time sleeping and they tend to move fairly slowly in order to conserve energy, although they can be very playful, especially in captivity where they can access higher quality foods.

Sadly, this playfulness and supreme floofyness is a bit of a problem for the wild Red Panda population. There is demand for wild caught Red Pandas in the pet trade and they are hunted for their thick fur right across their range through the foothills of the Himalayas, despite being protected by legislation in every country.
