Enter the Dragon

Darter by Scott Guiver

Yeah I know, the title’s not very original but it’s all I could think of.

This year I’ve made the effort to try and identify more of the creatures that own four wings. I believe this beauty is a Common Darter, but please do correct me if I’m wrong.

The picture below isn’t aesthetically one of the best shots I’ve taken of a creature with four wings this year, but hey, who cares – it’s definitely a Norfolk Hawker!

“It’s all about refraction ” said the dragonfly to the beetle.

Why do so many insects have beautiful metallic colours?

I typed this question and various forms of it into Google , I expected the results to contain either brief and precise explanations from insect forums or detailed scientific papers from studies into this question. Maybe I was being lazy, I only looked at the first couple of pages of each search – does anyone look any further than that!? But I didn’t find a satisfactory explanation. I found out how they appear coloured this way by the refraction of light on features in the structure of their exoskeletons and that maybe the resulting effect may confuse some predators  (the Common Lizard in the photo below was aware of the beetle, but did not attempt to catch it. I could only speculate on the reasons why).

But then I found myself asking another question that could not be answered by another lazy google search: Could this feature also be a non visual one , i.e. sound waves refract just like light waves do, therefore could this feature  be a good one to avoid being munched by a bat? If anyone can answer these questions or point me in the right direction, I’d love to know. Thanks.

I have now been active on my blog for about a month. Yesterday I had the highest number of views in one day (119 – thank you viewers!). But on closer analysis of the stats , I noticed something :

The post with the highest number of views was The Dragonfly Blues , my  27 th post , it had 27 views. hhmmm interesting!

What’s in a number?

Some maths:

27 is the only positive integer  that is 3x the sum of its digits. (2+7 x 3=27)

–  27 cubed is 19,683.   1+9+6+8+3= 27.

–  27 is the sum of the integers from 2 to 7. (2+3+4+5+6+7=27).

–  27 straight lines on a smooth cubic surface make the perfect cube ,(Cayley-Salmon theorem) – I’ll take their word for it!

Some trivia:

– The human hand is made up of 27 bones.

–  Florida is the 27 th state of the USA.

–  In ancient Inca culture there were 27 roads to El Dorado.

🙂     Happy Friday WorLdpress.

The Dragonfly Blues.

The Dragonfly Blues

Landing on the moon,

Disembarking from a wooden spoon,

Flying on kitchen utensils,

Is not as fast as sharpened pencils,

Stepping off to lunar land,

Or drinking down the Grand,

It’s all alien to me,

Polystyrene ships in a heavy sea,

Feathers, Little Egret, so white and pure,

High grade coke, once a rich mans lure,

Make no comparisons, blinkered fool,

Progressions hand ,caresses a building tool,

Treeless roots beneath our feet,

A thousand under every street,

A dragonfly darting,

Or an old man farting,

Methane and the permafrost,

Accountants add the cost,

Broken hearts and broken lives,

Naked forests , Amazon fires,

Only what’s chosen , makes the news,

I’ve got a case of the Dragonfly blues.
