Some Insanely Cool Insects: Glow-worms, Sawflies and Hawkmoths


Keeping out of the sweltering midday sun has become necessary to prevent myself from melting into a pool of sweat. But this great weather does mean that the evenings and early mornings are perfect for getting out and about, and spotting all of the insects that are basking in the glory of the sun's warmth. 

Blackbird chicks have dominated the top of the garden, with their cute dumpy appearance, short stubby tail and wide yellow mouths. I could hear the chirping of a chick underneath the hedgerow, so had a little rummage to see if I could spot the youngster. There, peering out of the undergrowth, the blackbird chick sat impatiently waiting for its mother to bring food to her. 

Peering through the undergrowth

Later that day, the chick had moved up to the top of the garden and bounced between cover to get fed. 

Sneaking behind the bricks

Great job by the mother!



But now, onto some of the insect highlights over the past week or so. Clinging to the silver-birch at the top of the garden, sawfly larvae hung in defense like the strongest of gymnasts.




Not strictly an insect, but this beautiful garden treat definitely falls into the creepy crawly category. A, what I believe to be, garden orb weaver spider (correct me if I am wrong - the markings on the abdomen look slightly different!). 

In wait of prey...

Working late has its advantages. Working late in a zoo built on the side of the downs helps too. A twinkle in the grass, at first I thought it was glass reflecting the torchlight. But upon closer inspection, the sparkling object revealed itself to be the glowing rear of a female glow-worm. My first glow-worm, and I was thrilled to see such a spectacular display of bioluminescence. Of course, this glow attracts the males which are glow-less but can fly. 


Some mighty fine glowing! 

Magic! Waiting for the flying male to mate with


The very next morning, I arrived back after a tour of the zoo, and was greeted by the cafe staff with a coffee mug with holes punched into the lid. Inside was an exotic moth, bright pink and black stripes across its abdomen, with a wing length almost the size of my palm. This was in fact a privet hawk moth, a species I have never seen before, and one that I thoroughly enjoyed getting to admire in such close proximity. Phenomenal antennae!



Phwoar!

Released back into the wild


After my recent mini-garden survey in my previous post, I just can not help but look at the plants in the grasses. Whilst Rachael and I enjoyed tea and scones at the picturesque site of Houghton Mill in Cambridgeshire, I could not help but notice at least three grass species, directly underneath our feet! Not everyone shared my enthusiasm mind...

Some grass...

One particular advantage of having one of these more modern smart phones, is that their cameras are fairly decent, and are extremely portable. Because of this, I managed to photo the glow-worm, hawk moth, and casually snap bits and bobs quickly and easily without the need for the actual camera. Below, one of many fox-glove that have sprung up amongst the woodland around Ashridge...

Back home, and walking with Ellie, in the cool, warm evening sun. The air was warm, the tough grasses prickly against my calves. The sun dipped towards the horizon behind the woodland beyond the fields. The wheat glowed gold with the tint of the setting sun.

Between the trees
What a wonderful and sunny way to end a blog whilst I sit in my shorts baking hot in the midst of this heat wave that has swept the country! Thank ya'll for taking the time to read and/or gorp at some dodgy photos - expect a North Norfolk special in the next post!

Mini Garden Survey: Perfect lawns are for prats!

The sun was shining and a faint breeze in the air. I put my feet up onto the garden bench, leaned back in my chair and watched as the swifts screamed, twisted and turned like boomerangs, emerging from the bright blue of the sky, altering their course as they catch insects mid-flight.

As I looked down, I noticed that  there were plenty of things going on in the grass. Which gave me an idea... I wondered how many plants and insects were in a simple lawn that had not been mowed for a week. I chose a small area, right in the middle of the lawn, and had a little rummage in a patch about a metre by a metre. It was quite a casual survey, only taking ten minutes or so, but I guess one that could easily be repeated in future, and maybe in more detail!

The Results! 

First, I set about identifying the plants in the patch. Forgive me for any errors in identification, my botanical skills have lots of room for improvement! Some photos have been taken with my camera phone through a field hand lens, which worked quite well despite the odd bit of vignetting on the right hand side of the photos.

Daisy Bellis perennis
Dandelion Species Taraxacum sp.
White Clover Trifolium repens


Lesser Trefoil? Trifolium dubicum
Selfheal? Prunella vulgaris


And that is not forgetting the grass species in the lawn, of which I could distinguish at least two, but did not ID to species level.

There were a few insects that paid the patch a visit or two. Including two species of ant, bumblebees, honey bee and an insect that came so briefly I could not get a good look and photo to ID properly.

Yellow Ant Lasius flavus
Red-tailed Bumblebee Bombus lapidarius
Honey Bee Apis mellifera
Bumblebee species?
I have no idea! 

 So what have I learnt from my micro-study? Even small patches of lawn can be species rich and be host to a fairly diverse amount of wildlife. Also, my plant and insect ID could do with some practice! A more in depth study of the patch and a longer observation could give better results. What about species in the soil? What about a transect across the lawn?

I was shocked to find that a lot of the plant species identified are quite often referred to as weeds (of course, there is no such thing!). Which I find is a bit of a tragedy. Anyone that does not want a splash of daisies and clover across their lawn, with frequent visits from the wonderful bees and insects that choose to feed from these, is insane. I curse those with immaculate, carpet-esque lawns, devoid of life.

Also, check out Notes on Natures recent fascinating post about the plants that grow in his lawn when left for a few weeks http://notesofnature.blogspot.co.uk/2013/06/in-garden-whats-in-my-lawn.html. Its a great blog, with some very interesting reads!


On a slightly different note, meet Casper. The over-groomed, semi-bald African Grey. Unfortunately she needed a new home, and we were lucky enough to be able to provide her with one. :)

Casper!

I hope you enjoyed reading about my mini survey, the next blog will include a walk to Warren Villas (amazing!) and a blackbird chick... Thank ya'll!
