I didn’t expect anyone to get the precise sources.  The common element was that all the insects come from bird illustrations that have been published and republished.  Philip was close in that regard.  As I don’t know much about insects myself I was impressed by Steve Holliday’s typically field-knowledgeable responses below, verging on the unbelievable.

 

I won’t recirculate the original graphic.  This is a more informative view of the sources, in a slightly different order  :

For those interested –

 

Number 1 was the familiar Red Admiral of the European countryside, sitting on a blackberry leaf in Henry Richter’s drawing of Whitethroats, in Gould’s ‘Birds of Great Britain’ .

 

Number 2 was also from a Richter drawing, the Pied Butcherbird in Gould’s ‘Birds of Australia’.  About all I can tell you is that it is a stick insect or ‘phasmid’.  Gould probably called for its inclusion, because he said in the text that ‘ ... large Phasmiae come within the list of its ordinary diet’.

 

Number 3 was a flying stag beetle, being eyed by the improbable Eagle Owl in the painting by Edward Detmold (1883-1957).  Must be some symbolism in there somewhere.

 

To show how little I know about insects, I chose number 4 out of a host of insect-adorned paintings in Audubon reproductions because I thought on a quick look, subject to checking, that the large dark insect flying up in the tree was a Periodical Cicada, of which the southern US species emerge each 13 years.  In fact it lacks the blunt head and it has but a single pair of wings, so is a fly.  Audubon himself wrote that the relevant Black-billed Cuckoos (before he shot them, near a swamp in Louisiana)    ‘were in pursuit of such flies as you see figured’.  But what kind of fly?  Because of the thick black body and patterned wings (more obvious in the watercolour) I wonder if it could be one of the ‘bee flies’  Anthrax spp.  Anyway, that’s my guess.  (Both the genus name and the disease name come from the Greek ‘anthracitos’ – ‘coal’.)

 

Number 5.  William Hart drew the Ribbon-tailed Drongo for Gould’s ‘Birds of New Guinea’ and included the large butterfly.  It is a male of the Ornithoptera  or ‘Birdwing’ group - well done Julian T.  This unusual drongo is endemic to New Ireland in the Bismarck Archipelago so the butterfly should have been O priamus urvillianus – D’Urville’s Birdwing.  However, from pictures it seems to me that in all variations of urvillianus the males are, by contrast with other male Ornithoptera, black or very dark on the upper surface of the wings.  It seems likely that Hart was simply handed any old Ornithoptera from the collection in the British Museum (Natural History).  “They won’t know the difference”, Gould would have said, as he was getting on a bit, and died before completion of the project, and none of them had been to New Guinea.  As it happens, the insect is drawn life-size in considerable detail, so an Ornithoptera expert could probably identify the subspecies (or species) that Hart used as his model.

 

 Number 6.  More than half of the illustrations for Gregory Mathews’ ‘Birds of Australia’ were prepared by the Danish-born Henrik Gronvold (1858-1940).  Many of the drawings, although set against some kind of background are far from life-like and have little adornment.  An exception is the Ground Cuckoo-shrike plate, in which, under the critical stare of a GCS,  Henrik included a beetle.  As he spent many years in the British Museum (Natural History) preparing precise illustrations of birds and other animals for scientific publications, I think it unlikely that he would have just dashed off an imaginary beetle or used one that does not occur in Australia.  He could easily have sketched something from the museum’s Australian collection.  I am not able to take the identification any further.

Ha, I’ve missed your quizzes!

 

1.       The Red Admiral of Britain and most of the rest of the Northern Hemisphere

2.       A stick insect in somebody’s beak

3.       A male stag beetle

4.       An interesting looking true fly  (order Diptera) of some sort or other

5.       A male birdwing butterfly with a mystery foot on it, don’t know which spp, males are mostly green and black, and there are 3 now recognised in Australia alone, as well as a fair few more from the islands to our north. One you would remember from your New Guinea days?

6.       Another beetle, beyond that I don’t know. Unless it is Alexander Beetle.

 

And what do they have in common? Don’t know. Wings? Something to do with the illustrators? Would be interested to know the sources of the illustrations.

 

regards

 

Steve

Can you identify these birdwatchers’ insects?  Not necessarily Australian.  Generic answers will suffice.  What do they have in common? 

 

I correct -   Pass

2 correct -  Very good

3 correct -  Excellent

4 correct -  Unbelievable

5 correct – Uncanny
