The Spider and the Fly

20120603-101636.jpg

“Will you walk into my parlour?” said the Spider to the Fly,
“‘Tis the prettiest little parlour that ever you did spy;
The way into my parlour is up a winding stair,
And I’ve a many curious things to shew when you are there.”
“Oh no, no,” said the little Fly, “to ask me is in vain,
For who goes up your winding stair can ne’er come down again.”

“I’m sure you must be weary, dear, with soaring up so high;
Will you rest upon my little bed?” said the Spider to the Fly.
“There are pretty curtains drawn around; the sheets are fine and thin,
And if you like to rest awhile, I’ll snugly tuck you in!”
“Oh no, no,” said the little Fly, “for I’ve often heard it said,
They never, never wake again, who sleep upon your bed!”

Said the cunning Spider to the Fly, ” Dear friend what can I do,
To prove the warm affection I’ve always felt for you?
I have within my pantry, good store of all that’s nice;
I’m sure you’re very welcome — will you please to take a slice?”
“Oh no, no,” said the little Fly, “kind Sir, that cannot be,
I’ve heard what’s in your pantry, and I do not wish to see!”

“Sweet creature!” said the Spider, “you’re witty and you’re wise,
How handsome are your gauzy wings, how brilliant are your eyes!
I’ve a little looking-glass upon my parlour shelf,
If you’ll step in one moment, dear, you shall behold yourself.”
“I thank you, gentle sir,” she said, “for what you’re pleased to say,
And bidding you good morning now, I’ll call another day.”

The Spider turned him round about, and went into his den,
For well he knew the silly Fly would soon come back again:
So he wove a subtle web, in a little corner sly,
And set his table ready, to dine upon the Fly.
Then he came out to his door again, and merrily did sing,
“Come hither, hither, pretty Fly, with the pearl and silver wing;
Your robes are green and purple — there’s a crest upon your head;
Your eyes are like the diamond bright, but mine are dull as lead!”

Alas, alas! how very soon this silly little Fly,
Hearing his wily, flattering words, came slowly flitting by;
With buzzing wings she hung aloft, then near and nearer drew,
Thinking only of her brilliant eyes, and green and purple hue –
Thinking only of her crested head – poor foolish thing! At last,
Up jumped the cunning Spider, and fiercely held her fast.
He dragged her up his winding stair, into his dismal den,
Within his little parlour – but she ne’er came out again!

And now dear little children, who may this story read,
To idle, silly flattering words, I pray you ne’er give heed:
Unto an evil counsellor, close heart and ear and eye,
And take a lesson from this tale, of the Spider and the Fly.

Mary Howitt, ‘The Spider and the Fly’ (1829)

A new world beckons

20120522-151652.jpg
A freshly hatched nymph looks out on a new world.

I was pottering around the herb garden looking for some buggy subjects for my ever-hungry macro lens when I thought I saw a greenfly. Closer observation revealed this pretty little speckled bush cricket nymph. Speckled bush cricket (leptophyes punctatissima) nymphs shed their skins six times. Each version is called an instar. I think this tiny nymph is a newly emerged first instar.

The full adult version, as pictured below, can be found in the garden from about late July onwards. I have found the little nymph in the same place every day since I took its picture. I will follow its progress and try to get some more shots as it grows.

For more information on speckled bush crickets and some super shots see this blog.

Macro economics

20120520-120158.jpg

I have found that people often assume that they will not be able to do macro photography without expensive kit. Certainly, I now enjoy using Canon’s 100mm L IS macro lens on the full-frame 5Dii, hardly inexpensive equipment. However, looking back through my macro shots I was surprised how many, fairly decent, images I had achieved before I bought my current kit.

20120520-120639.jpg

Most of the shots in today’s post were taken using my 400D, a fairly old, entry-level DSLR with only 10mpx at its disposal. All of them, except the last one, were taken using the Sigma 50mm f2.8 EX DG Macro, a nice little lens that you can pick up for £250 or less.

20120520-120910.jpg

True macro lenses have a fixed focal length. They are prime lenses and, therefore, usually produce higher image quality than a zoom.

20120520-121051.jpg

A 50mm prime has many uses beyond macro. 50mm is a nice length for portraits, for example. So your macro lens is a good and versatile purchase.

20120520-121234.jpg

I recently read in a photography magazine that anything less than 100mm was too short for shooting insects. Hopefully, this post proves otherwise.

20120520-121440.jpg

Another item often touted as essential for macro work is an expensive flash, usually a ring flash for insects. Not so. All of my macro work is done in natural light.

20120520-121615.jpg

If you are not yet ready to buy a macro lens, there are other options. Extension rings, dioptres, or reverse mounting a regular lens, all achieve good image magnification although handling them well takes some practice.

20120520-121913.jpg

Finally, do not assume that without dedicated macro equipment, close-up work is out of reach. This final shot was taken using a 24-105mm zoom lens.

20120520-122159.jpg

Outdoor macro photography is my favourite genre. You can do it at almost any time of day and it is best when the sun is not shining. Perfect for those of us who live in a country the sun has forgotten and whose other commitments prevent them spending hours waiting for the light at sunset and sunrise.
Are you already a macro fan, or are you thinking of taking it up?

Ladybird, ladybug

20120516-131525.jpg

The last in my mini-series about the aphid, ant, ladybird relationship, is the top predator, the ladybird, or ladybug if you are American. Ladybirds are beetles of the family coccinellidae. They are probably the most easily recognisable beetle thanks to their characteristic bright colouring.

20120516-131909.jpg

Of the world’s 3500 species of ladybird, 46 live in Britain. Probably the most common is the seven-spot ladybird, coccinella 7-punctata.

20120516-133130.jpg

Although many types of ladybird will eat other insects, their favourite meal is aphids, which they will hoover-up without being in the least deterred by ant-shepherds.

20120516-132219.jpg

May is the main month for ladybirds to mate.

20120516-132252.jpg

In recent years, Britain has seen an influx of the Harlequin ladybird, harmonia axyridis. This large ladybird is considered to be a potential threat to indigenous species. It is a voracious hunter and its larvae will eat the larvae and pupae of other ladybirds. It may also mate with indigenous species.

20120516-132533.jpg

The Harlequin is difficult to identify accurately because its colours vary so much. I think, however, that in the picture above, both ladybirds are harlequins, despite their very different appearances. One clue is that Harlequins usually have brown rather than black legs.

20120516-132733.jpg

Ladybirds hibernate through the winter. Here a group of harlequins sleep huddled together.

20120516-132836.jpg

Somewhere on my hard drive are images of ladybird larvae and pupae. When I find them, I will add them here. In the meantime, I leave you with the well-known nursery rhyme:

“Ladybird, ladybird, fly away home
Your house is on fire,
And your children are gone”.

20120516-132904.jpg

No bugs tomorrow, I promise!

The little bug that could

20120514-203412.jpg

Welcome to the second instalment of my three-part series on the aphid, ant, ladybird relationship. If you don’t like ants, look away now!

20120514-203641.jpg

Less than .5% of the world’s species of ant live in the UK. It is mostly too cold and wet for them, something not difficult to believe given the spring we’re having! By far the most common is the black garden ant, Lasius Niger.

20120514-203743.jpg

These tough, fast, little ants live in colonies of up to 15,000. They eat insects, seeds, nectar and even the bodies of their own dead.

20120515-085529.jpg

As illustrated in an earlier post, they have a particular liking for the sticky honeydew secreted by aphids and will climb bushes to “herd” aphids, protecting them from predators. They obtain the honeydew by stroking the aphids with their feelers!

20120515-085723.jpg

On certain still, warm days each summer, males and queens will emerge from the nest and take to the wing, mating in flight. The queens then shed their wings and start new nests. The males, their sole purpose fulfilled (if they are lucky), die. Environmental cues lead to all the nests in a locality releasing their males and queens at the same time. This enables inter-nest mating, ensuring genetic diversity.

20120515-085824.jpg

The study of ants is called myrmecology. This made me think of Achilles’ myrmidons so I looked up the etymology of the word and learned my new thing for the day! According to myth, Zeus made the Myrmidons from a nest of ants. Another meaning of myrmidon is a faithful follower who carries out orders without question.

20120515-085903.jpg


“Next time you’re found, with your chin on the ground,
There’s a lot to be learned, so look around.

Just what makes that little old ant
Think he’ll move that rubber tree plant?
Anyone knows an ant, can’t,
Move a rubber tree plant.

But he’s got high hopes, he’s got high hopes,
He’s got high, apple pie, in the sky hopes.

So any time you’re gettin’ low,
‘Stead of letting go,
Just remember that ant,
Oops there goes another rubber tree plant.”

“High Hopes” Cahn/Van Heusen

Aphids of every hue

20120514-093533.jpg

A few weeks ago, I told a story about a conflict between three species of minibeast in my garden. This week, I thought I might take three days to focus on each of those same three species individually. I promise to do something non-buggy on Thursday.

I am starting with the bottom of the food chain, the lowly aphid. The top image is hot off the presses, taken in my garden yesterday. We actually had some sun this weekend! Back to rain today though. Anyway, I call it “Bringing up Baby”. Babysitting is such hard work, especially when the toddler will keep running away from you!

20120514-094154.jpg

Aphids are a lot less attractive in numbers, especially when sucking the life force from one of my rose bushes. The picture above makes me think of sci-fi and contagion-style movies. Euch.

20120514-094403.jpg

Still, aphids are a vital part of the garden food chain, like the wildebeests or antelopes of the African plains. I call the shot above “The Bubble Trap”. A blackfly is caught in a double trap of web and water droplet.

Here’s another capture of the same doomed aphid:

20120514-094659.jpg

All that is left of the aphid in the next shot is a single wing:

20120514-100721.jpg

Singly, however, the greenfly remains an unexpectedly graceful creature, its delicate form suggesting vulnerability:

“He didn’t want to stop cutting, and hacked away so furiously that he shook with the vibrations, wedged between his two levels of rock, like a greenfly caught between the pages of a book which threatened to slam suddenly shut.”
Emile Zola, Germinal, trans. Peter Collier

20120514-102802.jpg

Tomorrow, it’s the aphid farmer’s turn, the garden ant. I bet you can’t wait. 😉

Forgotten skills?

20120509-105620.jpg

I am a member of a camera club and often enter images in their competitions. One night I entered this image, called “Floral Fireworks”. It did very well, earning me 10 out of 10. The judge was complimentary but she assumed the blurring had been achieved in Photoshop. In fact, this shot was, apart from a small crop and the frame, straight out of camera. The blur is simply the result of using a wide aperture (f2.8) and focusing on the centre of a cup shaped bloom. The petals, being nearer the sensor than the centre, are soft.
I think Photoshop is a powerful and effective tool and I enjoy using it. But I wonder whether it has caused us sometimes to forget what can be achieved in camera? For me, the most powerful tool of all is understanding how my camera works. What do you think?

Bee fly

20120508-161843.jpg

The subject of my natural history post for this week is the bee fly or bombylius major. This bee-mimic is common in my part of the world (Southern England) in early spring.

20120508-162143.jpg

Its rather imposing appearance can lead people to assume that it is dangerous but it cannot harm you: that long proboscis is merely a very efficient nectar guzzler. In fact, I think the bee fly is rather cute. Just me, perhaps.

20120508-162357.jpg

They certainly look quite cute on the wing, with their spindly legs flying out Superman style from the chubby body. However, while they may not be harmful to humans, they have a sinister life cycle if you happen to be a bee.

20120508-162956.jpg

This bee mimic lays its eggs by the nests of solitary bees. When the larva hatches, it uses a crown of spines on its head to batter its way into the cell of the bee pupa and slowly sucks the pupa dry.

20120508-162906.jpg

Afterwards, the gorged larva pupates and finally emerges in its final form by battering its way out of the cell.

20120508-163209.jpg

Needless to say, I have not been able to take photographs of the full life-cycle, just the disingenuously cute, fluffy fly.

20120508-163342.jpg

For some more (and frankly better) pictures and two poems (yes!) about bee flies, visit my friend Giles Watson’s Flickr photostream. The second poem (which treats the life cycle) appears in a comment there.

PS Some of the images appear pixelated here.  They do not in the files I uploaded.  If anyone knows what I’m doing wrong, please can you help?  It’s a shame for them not to appear their best.
