There are just too many great photos to put in one blog

Its the little things... that really matter

Aprils Insects

I hadn't, until very recently, appreciated the vibrancy and diversity of bees and wasps that rivals the glamour of the butterflies that have recently been highlighted on the blog.

It all came about while inspecting the emerging autumn blooms of one particular Dune Soapberry.  I camped out here for a few hours and while initially I was struck by the number of blue butterflies and others stopping by it was soon apparent that wasps had much more of a fancy for the nectar and pollen this tree provides. 

And then, yesterday, I spent the day at Cumberland Nature Reserve, I was invited to tag along with the Witteveen family for a picnic and to make a plan with the landowner about revitalising a regular bird ringing station here.  We couldnt have planned a better day, one of the classic winter days, the air was cool and calm, the sun beating down onto the canopy of paper-bark acacias that cast beautiful shadows among the picnic area.  A zebra and foal loafed around just off to the side while we ate and enjoyed the lazy pace of the day.

While the bird list was just reasonable with 33 species, there were some interesting species that could be had in future ringing weekends: groundscraper thrush, golden-breasted bunting, and grassbird to name a handful of my picks.  Also there seemed to be a guarentee of long-crested eagles as they nest on an approaching tree, while it was interesting to see black-breasted snake-eagle there too.

By infact, my attention was forever drawn to the butterflies… yup, its been a recent focus of mine, and the new Canon sx50 is getting tested on its macro and short focal distance capacity. Pretty pleased with the results.

To finish off a trilogy of greebly interests, and to wrap up the most recent blogging emphasis on entomological critters, here are a few more dragons, and my first pictures of damsels.  All taken at one lilypopnd in Plett last week.

Dragons and Damsels

The last two days have been very cold, and snow has fallen at Sani Pass in the Drakensberg.  Winter is just around the corner!

As summer comes to a close, I suppose the vibrant and abundant insect life will begin to shut up shop.  So in addition to the butterflies featured last week, I though I’d highlight some of the wonderful dragonflies seen over the summer.  Sadly again, there is only a small selection of photos that I would like to pursue and expand on, with a conspicuous lack of Damselflies. In South Africa there are 160 species of Odonata (which include both the Dragon- and Damelflies), so, a long way to go then.

My interest peaked back in August last year when Warwick Tarboton contacted me about his planned trip to Mongolia. I found on Warwick’s website a fantastic accumulation of dragonfly photos.  Please please peruse these!  Warwick is an all-round naturalist, and has a depth of knowledge developed from a lifetime of keen attention and sharp senses that only few people possess.  The new Roberts Birds Nests & Eggs is simply spectacular.

To expand on the theme. The New Zealand Bush Giant Dragonfly Uropetala carovei is the largest NZ endemic with a wingspan of 13 cm.

There were also a couple of pretty dragonflies in Mauritius. Through the long standing MWF grapevine, a bit of an entomologist from Mauritius got in touch to help me identify these species, so thanks Andrew Skinner ! (who collected over 900 beetle specimens while working on the Mauritian kestrel project for several years - thats dedication!)

The ancient ancestors of the order Odonata were the top predators of the Permian and Carboniferous food chain, their apex predator status enabled them to become the largest flying insects ever known, the extinct genus Meganeura, ancestor relatives of dragonflies named, and I love this - Griffinflies, includes Meganeura permiana which had a wingspan of 71 cm!  This appears to exceed the theoretical threshold of size for insects, but may have been possible by higher atmospheric oxygen concentrations and respiratory pumping of the Griffinflies tracheal system. Looking for a picture to show off the magnificence of Meganeura I found the blog of Leandro Sanches Costa, a biologist and sculptor who makes some pretty amazing reconstructions of extinct animals!

Psyches Metamorphosis

I’ve been busy with plenty of office work and life events which are difficult to express.  So time for a different perspective. The year 2013 has been nothing if not interesting.  I have had to face some gargantuan questions and challenges.  While facing these challenges head on, I have had many moments both of ecstasy and of troubling wobbles.  So while this kind of business doesn’t provide the most compelling blog posts, I thought a nature-oriented metaphor could

Metamorphosis

A wonderful transition that the sluggish, legged-worm creatures we call caterpillars take on their journey in life to being bright, expressive, often gaudy, creatures of flight.  The ancient Greeks used the word Psyche, meaning soul (now mind)

To put it in context, let’s start with a little bit of homework.  The first 20 years of my life, in New Zealand, was spent in great ignorance of butterflies and moths.  Later, with a couple of years of entomology courses at Massey University, I learned that NZ’s Lepidoptera diversity bears such resemblance to other groups of animals on this long isolated, remote, south pacific land.  The butterfly diversity is particularly embarrassing with only 13 native species, however the remaining 1800 species are of moths, with a very high endemism of about 90%.  Moths though are mostly covert and camouflaged creatures of the night

South Africa in contrast, is a place of mind-blowing diversity for a humble Kiwi.  There are 666 species of butterfly, and further, there are more than this number of brightly-colored day-flying moths alone, with a wild estimate of some total of 10,000 species of moths

So I have given them much appreciation and paid some glancing attention of the butterflies and moths while out at my eagle sites.  Summer has been a wonderful spectacle of emergence

Having delved into my collection of photos from this year gone, I’ve found a few nice photos to share here.  I’ve also added one or two of Glen McLean’s photos, who has helped identify some of these species, and is making a good start to developing a digital collection of the butterflies of South Africa. Maybe in coming years I’ll be seen wandering gardens with my butterfly net and camera

Take a look at the website of the Lepidoptera Society of South Africa, the home page has a magnificent photostream

The ADU’s Virtual Museum is a depository and citizen science project of digital specimens of all types of wildlife. And submitting digital butterfly specimens will contribute to the SABCA, a joint project of Lepsoc, ADU and SANBI to revise the Atlas of SA butterflies distribution and conservation status
