The Week on Sunday #31

♦ Let’s open this Week on Sunday with video by Stanislav Snäll and John Hallmén, working in the field and showing some simple flash diffusion methods:

 

♦ Swedish photographers John Hallmén and Stanislav Kind are professional photomacrographers who run the website Makrofokus, an excellent resource for those wishing to learn more about focus stacking. Be sure to follow the MakroFokus Facebook page for regular updates on their work!

 

♦ The new laid-back and relaxed (see A Tale of Two Blogs) Ted MacRae  has a post on his latest Canon MT-24EX twin flash diffuser. Check it out!

 

♦ And on the science side of things, a fascinating video documentary on insect dissection. Such complexity – and even beauty - within!

Lots of great information in this video, and a look into the cool technology science is using to explore bug wonder!

 

♦ The last week was spent in continued spring cleaning in our home garden , with a mid-week break taking the Small-group Macro Workshop down to the great people at the Crop Diversification Centre South in Brooks, Alberta! We had a great time looking at how to get the most out DSLRs and then, after a yummy lunch (in which someone forgot to bring the buns!) , we had a session on the many paths to making macro. We even had time to wander around the grounds to practice with some equipment set-ups. Thanks to Shelley for inviting me down, and to Scott, Simone and Mike for participating.

* I also received a bonus cutworm specimen – chock full of parasites - like the one in Shelley’s timelapse video below.

 

Cool, eh!

Until next week!

The Week on Sunday #23

♦ A splendid idea…

I remember the young Gerald Durrell did a similar experiment with bits of glass and beads, but this is a much more lavish process!

♦ BBC has a new buggy season ahead: take a look at all the bug-wonder taking place in 2013 at Alien Nation. BBC Four supersizes the insect world in an ambitious new season.

♦ An extensive article on the plight of bees in the Fight of the Bumblebee over at The Walrus.

♦ Piotr Naskrecki is one masterful macro photographer!  Part of that skill is patience, and he lost a lot of sleep coming up with the shots for this time-lapse of a chinese mantid shedding its exoskeleton.

Visit The Smaller Majority for more on this sequence.

♦ And sealing this Week on Sunday? Sean McCann gives another insight into a low-cost macro solution in Cheapskate Tuesday 6: A simple flash bracket. Variable-friction arms are the latest trend amoung many solutions on how to place a flash over your subject.

That’s all for this week.

Free eBooks by Jean-Henri Fabre.

Fabre at home.

Fabre at home.

I was only about 12 years old when I first heard about Jean-Henri Fabre, while reading about Gerald Durrell‘s childhood in the book Birds, Beasts and Relatives. Gerald’s brother Lawrence, recognising his interest in bugs, gave him a copy of  The Sacred Beetle and Others

by E. J. Detmold: Fabre's Book of Insects.

by E. J. Detmold: Fabre’s Book of Insects.

Forgetting my food, I tore the parcel open, and there inside was a squat, green book entitled The Sacred Beetle and Others by Jean Henri Fabre. Opening it, I was transported by delight, for the frontispiece was a picture of two dung-beetles, and they looked so familiar they might well have been close cousins of my own dung-beetles. They were rolling a beautiful ball of dung between them. Enraptured, savouring every moment, I turned the pages slowly. The text was charming. No erudite or confusing tome, this. It was written in such a simple and straightforward way that even I could understand it. ‘Leave the book till later, dear. Eat your lunch before it gets cold,’ said Mother. Reluctantly I put the book on my lap and then attacked my food with such speed and ferocity that I had acute indigestion for the rest of the afternoon. This in no way detracted from the charm of delving into Fabre for the first time. While the family had their siesta, I lay in the garden in the shade of the tangerine trees and devoured the book, page by page, until by tea-time – to my disappointment – I had reached the end. But nothing could describe my elation. I was now armed with knowledge. I knew, I felt, everything there was to know about dung-beetles. Now they were not merely mysterious insects crawling ponderously throughout the olive groves – they were my intimate friends.

At that time, in South Africa in the early 1970′s, I had no access to Fabre’s books.  They had no copies in the library (my second home for most of my youth), and the internet and ebooks were not even a twinkle in someone’s eye.

Thoughts of reading Fabre faded…

The Week on Sunday 20

Overwhelmed with work this weekend, so this Week on Sunday is short.

♦ Just out earlier this week, science blogger Carl Zimmer’s TedEd talk on the jewel wasp (Ampulex compressa) and the parasitic relationship with cockroaches…

This talk is based on the research: Gal, Ram; Rosenberg, Lior Ann; Libersat, Frederic (22 November 2005). “Parasitoid wasp uses a venom cocktail injected into the brain to manipulate the behavior and metabolism of its cockroach prey“. Archives of Insect Biochemistry and Physiology 60 (4): 198–208. doi:10.1002/arch.20092. PMID 16304619.

♦ And also just released, this video teaser of an upcoming docu-drama on Alfred Russel Wallace, the lesser known compatriot of Charles Darwin who independently conceived the theory of evolution by means of natural selection. Wallace was a  naturalist, explorer, geographer, anthropologist and biologist, but for our purposes he was a bug-collector extraordinaire, who traveled throughout the Amazon and the East Indies in search of specimens.

There is a sort of Alfred Russel Wallace renaissance taking place now, and this year we will be celebrating his life and scientific legacy, as 2013 is the centenary of his death.. His writings can be found at Wallace Online, and his correspondence has also recently become available at Wallace Letters Online. You can stay up-to-date at the George Beccaloni’s Alfred Russel Wallace Correspondence Project‘s website, and at his Wallace 100 blog. Wallace’s collections can be seen at the Natural History Museum’s online Wallace Collection. And finally, I would be remiss if I did not mention Charles H. Smith, who was foremost in the effort to  keep the memory of Wallace alive, at The Alfred Russel Wallace Page.

So much out there to delight the lover of the history of science! Until next week…

Name this Fly

First attempt  at doing a focus stack with microscope images.

Last week a began setting-up for taking images through a second-hand microscope that I obtained many years ago. This is not a great photograph, but it is my first attempt at a focus stack using images made through a microscope. I have since found out a few ways that should improve the quality, but I thought I would post this to see if any Dipterists out there could figure out the ID from just the genitalia. Any takers?

Originally I was going to name this post “Name these Stacked Genitals”, but I don’t really want to compete for popularity with the Beetle-poop Geek. ;)

More details on the equipment/techniques (and lack there-of) later.

The Week on Sunday #14

Another week, another collection of buggy delights:

◊ A UK logger captures a woodwasp (horntail: Hymenoptera, Family Siricidae) at work…

◊ Ants are fascinating in themselves, but nature ups-the ante (so to speak) when it comes to the evolution of mymecophiles. Check out The Bizarre, Beetle-Biased World of Social Insect Exploitation at Scientific American blogs.

◊ And again from Scientific American blogs, a new weta species discovery, a weta that is already under threat.

Wotsa Weta? They’re the big flightless relatives of crickets and grasshoppers (Order Orthoptera) that live in New Zealand. Weta are the icons of  the Weta Workshop and Weta Digital,  the companies involved in special effects for the new The Hobbit. The Unexpected Journey movie that was released last week)

 

◊ Ed Yong over at Not Exactly Rocket Science features another post on bugs, this time on the fossil of an 110 million year old trash carrying lacewing larva. See the science at: De La Fuente, Delcios, Penalver, Speranza, Wierzchos, Ascaso & Engel. 2012. Early evolution and ecology of camouflage in insects. (Pay-per-view :( )

Ed also does a post on the amazing diversity of arthropods found in a small forest reserve in Panama. Check it out at Massive bug hunt reveals 25,000 arthropod species in a Manhattan-sized forest. Based on another pay-per-view article at Science, and see a slide show at National Geographic.

◊ Why Evolution is True starts a fly collection with The panoply of nature: more bizarre flies, and then follows it up with a Marvelous Spiny Ant.

Specimen: CASENT0178497. Species: Echinopla melanarctos. Photographer: April Nobile

My! Ain’t Nature splendorous?

◊ A little spider does something amazing on the web. Not in Charlotte’s distinguished hand, mind you, but an amazing bit of weaving here! See New Species of ‘Decoy’ Spider Likely Discovered At Tambopata Research Center (Hat-tip to BugGirl)

Look at that stabilimentum for a moment…it has eight legs! Does this mean spiders can count?

◊ And to close, a visit to Biodiversity Photography, for those who are interested in extended tropical photography workshops that have a distinct macro slant. While I can’t personally vouch for the workshops provided here, this is certainly the place I would start investigating would I ever have the chance to do an Amazonian photography trip!
