Who Is the Strongest?

READ  MORE   HERE   !

The half inch long dung beetles are the strongest living creatures on Earth. The male insects of this small species of insects can lift or pull 1141 times their own body weight. It is just like an average sized human carrying 80 tons or 72574.8 kg.

The news might take the shine off the title of World’s Strongest Man for Lithuanian Zydrunas Savickas; in 2009 he pulled a 70-tonne plane for 30m in under 75 seconds – this works out as only 411 times his 170kg body weight.

What makes dung beetles so strong?

Written Mar 26, 2016  by John Cassis

Small creatures all seem strong relative to their size, because their strength is relative to the cross sectional *area* of their muscles, not their weight or volume. If you double the length of an organism, the muscle cross-section goes up four-fold, but the weight and volume go up 8 fold – so you get bigger-er not stronger-er.

Another way of looking at it is that if a dung beetle can lift it’s own weight, then if it were to double in size, it could only lift half of its weight, without developing proportionally bulkier muscles.

This topic was famously covered in a 1928 essay by JBS Haldane, called “On being the right size”. I think it’s one of the most lucid science essays I’ve ever read.

Well, today at work I was barely able to lift a heavy box (to me) of files, weighing 15 kg.  My weight is 43 kg only, and if I take the load ( 15 ) and divide it by my personal petite weight ( of 43 kg), the result is 0.35 – which is a very rough SWR !!

STRENGTH TO WEIGHT RATIO

The Link above does mention working out this ratio uses averages including “Bench presses”.  You may, like me, innocently ask “But what IS a Bench press ??”    It is laying on your back and picking up weights on a bar and raising them up and straight above, in my terms.  Looks dangerous to me!  Wikipedia says:

The bench press is an upper body strength training exercise that consists of pressing a weight upwards from a supine position. … A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.

This page  HERE  mentions averaging out your ratios after different types of exercises, like squats and bench presses.  The closest I note that matches lifting a heavy (for me) box is the DEADLIFT –  read  HERE for info.

However, my “dead-weight Lift” involved a square shape and a dense solid mass, not a nice (looking) bar with weights at either end – this different structure makes a difference to your SWR.

The box I lifted was destined to go to an off-site storage company, that has a weight limit for each packed box (to be picked up and carried by their drivers) – – – and that Limit is 16 kg.  Not bad therefore that I could lift 15 kg, in my great opinion.

My 43 kg weight converts to 95 pounds.   I used   THIS  site to work out that (in theory) a 45 kg female could or should (if she wanted) lift a 26 kg dead-weight.   Speaking for myself, I had best do some intense “resistance” (strength) training, before I attempt picking up and lifting a BARBELL (bar to attach weights to)  with any weights on it at all !!

If you are keen to find out more about weight training equipment for human beings,  try  THIS  page.  It mentions the lightest weight plates (which affix to the barbell) are 2.5 pounds for Americans or 1.13 kg for Australians.  It seems an average barbell itself (without the weights at the end) weighs 20 kg.  It would be a great day when I  dead-lift 21 kg total (barbell + 0.5 kg weight at each end), let alone 26 kg -barbell plus a 3kg weight at each end.

That would mean a SWR of approximately 0.5 up alot from an SWR of 0.35 for my “dead-box” lift today (LOL).  I would be happy with being able to lift 50% of my body weight, even if the Weaver Ant can lift 10 to 50 times its body weight !!

Incy Wincy Spider – or Spider Woman

Little Miss Starwise stood by the train

Waiting for transport which soon came

There winched down beside her

a little black spider

which made Little Miss try to hide her

This is a little ditty that I wrote on Thursday 19 August 2015.  You may be able to tell the Story behind it.

I was waiting on the train platform to catch the train to work, when to my surprise, a beautiful small black spider winched her way down beside me on my right.  It was almost as though she ( why say “he” all the time ) was saying hello to me personally.  The thing is she landed on the concrete, much to my alarm, as there were many Homo sapiens species ( people ) standing restlessly around.  I tried sending a message telepathically to the spider, an image of being stepped on, which I imagined happening to me & it was not at all a pleasant thought.  She could have been Charlotte.

To my greater alarm, the train arrived, so I quickly moved protectively closer to her, to shelter her from giant feet.  Luckily, this little spider had her wits about her, and sensing vibrations on the ground, etc. she promptly began winching her way back along her beautiful thread, which was invisible to me, but must have still been anchoring her to her anchor point.  I was relieved until the girl standing a few centimeters from the spider on the other side to where I was standing, lumbered forward and I thought her crooked elbow or lurching steps may propel her into my spider friend.

Praying Mantis Medicine

Praying-Mantis3

Maureen Moss says that  “A beautiful portrayal of Virgo’s Divine maternal quality can be seen in the Praying Mantis, whose form actually resembles the shape outlined by the stars of the constellation Virgo.”

Wow, I am quadruple Virgo – the Sun, Uranus, Venus & Pluto in Virgo, with Scorpio rising!

A week ago on Saturday 30 May, Praying Mantis had my back – literally.

If the Praying Mantis comes into your life, the wisdom of this animal totem can be” be calm & peaceful“.

You need to calm yourself down, take it easy, and just blend in with your circumstances.

Gold Fly

austrian fly brooch

austrian fly brooch2

Here is my beautiful gold Austrian pin – Yes, it’s a Fly and she is all the way from Colorado, from an eBay seller,   oldsilverandgold.   This little Fly has a body of 14 carat yellow gold and wings of white gold, and red eyes.  It is a small fly, about 1/12 inch by 1/12 inch in size. She fastens in a kind of “floaty” way via the pronged spiral.  Call me daft if you like, but I am the same as David Attenborough, because both D.A. and I RESPECT all animals, quite different to saying that we love all animals.

Cladograms & Evolution – We are all related

Brontosaurus

Brontosaurus painting by Charles Knight

Phylogenetics orPhylogenetic systematics is a discipline and a field of biology that aims to identify and understand the evolutionary relationships among the many different kinds of life forms on earth, both living (extant) and dead (extinct)Cladistics uses an understanding of phylogenetics to look at the “Tree of Life” and uses a type of diagram called a Cladogram to represent branched “evolutionary relationships” or phylogenies.

Phylogenies are lists or diagrams that show the evolutionary paths taken by populations of organisms through many generations and over long periods of time.

Nomenclature is the devising or choosing of names for things, especially within a branch of science. Systematics or Taxonomy is the branch of biology that deals with classification and nomenclature of organisms or life forms.  A binomial (or two word) nomenclature is used to label and identify known species, using a Genus name and a Species name.  Please see    this   post here for in depth information about TAXONOMY.

Ode to the Grasshopper

Grasshoppers and Crickets

The grasshopper is an insect of the suborder Caelifera in the order Orthoptera. To distinguish it from bush crickets or katydids, it is sometimes referred to as the short-horned grasshopper. Locusts are the swarming phase of certain species of short-horned grasshoppers in the family Acrididae, and are known to be pests sometimes. However, I wrote the poem below about the Grasshopper years ago, after I caught a baby grass-hopper in my Bug catcher, and then wanted to capture what I thought are the unique features of “the Grass-hopper.”

Around 18000 kinds of grasshoppers are known to humankind today and can be found across the globe, except the north and south pole regions, where the temperatures are extremely low. They are predominantly found in the temperate regions.  The biggest Grasshoppers are about 4.5 inches (11.5 centimetres) long. Their legs are long hind legs that are used for hopping and jumping. The short front legs are used to hold prey and to walk.

The grasshopper  has two large eyes called compound eyes, one on each side of its head.  They are composed of many hexagonal lenses, which may mean the insect perceives multiple pictures of the same image.   More likely, it means each lens picks up certain intensities or pixels of an image, and looking through all the lenses puts just one final image together.  The grasshopper has three simple eyes  located between its compound eyes. Simple eyes have only one facet. They can see the difference between light and dark only.  Compound eyes are a way of seeing more efficiently at the high velocities that some insects travel at.   The more lenses, the higher the resolution (or detail) of the image.

If you must know why an insect’s compound eyes are so large, please read this link   here  on “insect vision”, which I tried to do, but it made my head hurt (because it is rather technical).

A Grasshopper’s hearing organ is called the “tympanum” and is located on the abdomen.   The abdominal segments each have a tiny pin-hole called the spiracle, and together, the spiracles allow gas exchange.   Spiracles are tracheal openings in the exoskeleton of a spider (Arachnid) or insect, through which air is admitted and expelled.  They are equivalent to vertebrate lungs, and where human beings inhale oxygen through their noses, Grasshoppers inhale it through their spiracles!

Beautiful Butterflies

A Queen Butterfly and a Monarch Butterfly feeding on a Mexican Sunflower (Tithonia rotundifolia) at the Butterfly Rainforest at the Florida Natural History Museum.

There are approximately 15,000 species of butterflies from the Class Insecta and the Order Lepidoptera (which also includes Moths).   The tropical belt holds the largest diversity of butterfly species, with South America having the richest amount.   Butterflies (and moths) are the only group of insects that have scales covering their wings, although some butterflies have reduced scales.  They differ from other insects also by their ability to coil up their proboscis.

A butterfly starts life as a very small, round, oval or cylindrical egg.   When the egg hatches, a caterpillar emerges and eats the leaf he/she was born onto.  Each caterpillar type likes only certain types of leaves.    When a caterpillar starts eating, it instantly starts growing and expanding.  The exoskeleton (skin) does not stretch or grow, so it grows by “molting” (shedding the outgrown skin) several times while it grows.   As soon as a caterpillar is fully grown, it forms itself into a pupa, also known as a chrysalis.   Inside the pupa, the caterpillar is rapidly changing.   A butterfly will emerge from the chrysalis, with the wings being soft and folded against its body, because the butterfly had to fit all of its parts inside of the pupa.
