Results from pet moth hatching

A few weeks ago I found a small green caterpillar on my rose bush. It might have well have had a label attached to it saying "generic green caterpillar" since it seemed completely average. It had no distinguishing marks at all really. The only thing I could do was to keep it as a pet, feed it and wait and see what it turned into. Did you know that for the majority of butterflies and moths in this country we do not know what the caterpillar stage looks like? There are just too many species and it is difficult to nurture some caterpillars successfully. By keeping this little dude, and photographing it, I could then match the caterpillar with the moth on Wild About Britain and potentially fill in a blank in human knowledge.
What did the caterpillar do next? Well, in the wild it was doing something typically moth like. It was making a den out of leaves. Using silk it glued the surrounding leaves into a protective shell and then hid during the daytime. This I suppose is to protect it from predators that would use sight to hunt it, such as birds. This protection also helped prevent it being found by ichneumon wasps that would use it as a host for its parasitic young. When in the jar on my desk it continued to do this leaf rolling and fed at night when it was dark.
Then on the 16th of August it spun a more secure cocoon out of sink and began to undergo metamorphosis. Its chrysalis is pictured above. Then it was just a waiting game.

Then 9 days later this pretty brown moth emerged. It was a Light Brown Apple Moth (Epiphyas postvittana). It turned out not to be scientifically significant as this is a well documented species. In the 1930s this moth was accidentally introduced to Cornwall and now is one of the most dangerous threats to the UK fruit industry. Because of this its life cycle is well known and photographed.

So all this time I was rearing a pest, but one of these days I may rear something previously un photographed. That would be really exciting.

on spotting the fifth dragonfly species of the season!

Just a quick note to tell you about this dragonfly I just spotted down at Watermead. This pretty chap is a Southern Hawker (Aeshna cyanea). It had just been pouring down with rain and so he was hanging on to and old cow parsley stem. After photographing the Brown Hawker down at Watermead, and the Common Darter, Ruddy Darter and Broad-bodied Chaser at Bradgate Park this is my fifth dragonfly species of the year. Wooooo!

Beacon Hill on a nice day

The last time I was up Beacon Hill was last winter after it had snowed. It was very different this time. The weather was warm and breezy and the rolling white clouds of August tumbled by quickly. The vista was large and unencroached by mist or haze. The yellowing fields of Nottinghamshire, Derbyshire and Leicestershire surrounded us. Whilst we ate a packed lunch a small herd of longhorn cattle (Bos taurus) slowly ambled through the picnic spot. Many city folk were seen scrambling up their picnics and fleeing to the relative safety of the rock outcrops. The cows unperturbed would stop by the picnic benches to scratch their necks on the wooden seats. The bull seemed as docile as the rest and with his head down munching and paying no notice of the silly people.
After spending some time on the summit we decided to walk around it in the anticlockwise direction. It wasn't long before we came across this amazing creature, a male Scorpion Fly (Panorpa communis). Now, I have seen several females of this creature before, and they are relatively boring. This male however is much more awesome as they have that enormous scorpion like sting at the end of their abdomen. This is one mean looking dude. Perfectly harmless though. Worth remembering also that this alongside the dragonflies and the damselflies it is one of the really ancient orders of insects.
A little further down the track and I became irresistibly drawn to the catkins on a birch tree. What interesting photographic subjects those are! Suddenly my eyes were drawn to a rather strange black, green and white bug that was ambling up one of the twigs. I had no idea what it was, and photographing it became tricky as it insisted on walking away every time I got close. Still stumped I ended up conferring with the insect experts on Wild About Britain who told me that this odd little fella is in fact a Mirid Bug (Heterotoma planicornis).
The last thing I noticed was that the beech tree had, in a selection of sizes, these pretty Birch shieldbugs (Elasmostethus interstinctus). Since I could see several of these I noticed that as they get bigger they change shape. They start out like green ladybirds and as they get older grow into their distinctive shield shapes. Thats the third shieldbug species I've seen this year. Wooo!

Going wild in the garden

Every time I go into the garden, I see something new. Take a look at this recent haul of new species (new to my garden) discovered amongst my roses and sweet peas.


Take a look at this beautiful female Hoverfly (Episyrphus balteatus). Hoverflies are very misunderstood. Though they look like wasps, they are completely harmless. Their larvae look like small green caterpillars and are so often grubbed off plants by gardeners. The funny thing is that the larvae is an aphid eating machine and so a welcome species in the garden.

There are 250 different species of hoverfly in the UK. Its interesting to see how many different types you can spot in your garden. So far I have spotted four different species in mine. The one above is a female Hoverfly (Sphaerophoria scripta).

You may have seen one of these Oak Bush Crickets (Meconema thalassinum) on your bedroom ceiling. These large grasshopper like crickets are nocturnal and unfortunately for them attracted to bright lights. What a confusing place the modern world must seem to them.

This dangerous looking chap is a Ichneumon Wasp (Pimpla hypochondriaca). In this photo she is cleaning her eyes with her front pair of legs. That scary pointy sting like thing is its ovipositor. This wasp wanders around looking for a caterpillar or grub to inject its eggs into and then leaves them to feed on the still living host. Nice!

This hansom chap is a Green shieldbug (Palomena prasina) that I found strolling across my rose bush, probably to fins some sap to drink.

Bigger still is this awesome Hawthorne Shieldbug (Acanthosoma haemorrhoidale) that I found hanging onto a sweetpea. He must have flown here looking for food.

Here a black and white Curled Rose Sawfly (Allantus cinctus) promenades on a rose leaf looking for a mate. Eventually he moved on.Finally for today take a look at this amazing Picture-wing fly (Tephritis formosa). A pair were eying each other up on my rose. After mating their eggs are laid in thistles and a gall forms.

Walking around Barkby Holt

I did this little exploratory hike the other day. I wanted to get into Barkby Holt and see what was in their. Here is my photojourney.




To be honest inside the wood, I couldn't see anything! The path was muddy and crossed with brambles and stingers. To protect my rather exposed legs I ended up walking through the whole place looking at my feet rather than inspecting the wildlife. I get the impression that this place would be awesome in winter on a mountain bike.
When you get out of the wood you end up back in farmland overlooking the pretty village of South Croxton. Here the wildlife is a little bit easier to see.
Check out this Cereal Leaf Beetle (Oulema melanopa). I found a couple of these loitering on the grass stems near the edge of the field above. These little bugs eat grass leaves and so are disliked by farmers who grow grass related plants. Still I think he looks quite pretty.
One thing that I like to do when walking around in the fields of Leicestershire is to sneak across field boundaries. That is, to silently slip over the fence and peak into the next field to see whats there before it has chance to run or fly away. Its surprising what wildlife you can catch off guard. Part of the path went through this conifer plantation. The rows of trees essentially cut off all view except for the line of trees at either side of you. As you move through the plantation a new row will open up and you can look down it. Again and again you go past row after row. Each new row was a new opportunity to sneak and peak to see what was hidden.

Check this out. A Brown Hare (Lepus capensis). In fact there was probably 20 or so of them and I got some fantatic close encounters. Further along I stopped to look at the White Bryony(Bryonia dioica) growing in the hedgerow. At this time of year you can see the berries of this plant hanging in the bushes like red grapes, almost.


This plant is one of those that I remember seeing back at infants school. As I remember there were only ever two plants that came onto my radar. Sticky plant and curly wurly plant. Well this is curly wurly plant. Let me explain, to help it climb it sends out little feelers that entwine other established plants and enable it to get a leg up. Check out these curly wurlies.
The last interesting thing that I saw was this bazaar looking Dancing Fly (Empididae empis).

All in all, an interesting wander.

In the garden of the Eco-house

Leicester has its very own Eco-house where folk can go and see how to live environmentally. It all seemed a bit stuffy to me. They recommended against buying windows that could open to save heat waste! However they seemed to have overlooked the great cooling qualities of a nice draft in the summer. The house was boiling, so much so that I ended up moving on to enjoy the garden slightly faster than I expected. I saw this Green Shield Bug (Palomena prisina) enjoying a cultivated ragwort like plant.

Another creature found in the garden was this Speckled Bush-cricket (Leptophyes punctatissima). It seemed to have climbed to the top of a flower stem and wanted to go further and so was reaching for a nearby flower.

On the buddleia I saw another wonderful Painted Lady (Vanessa cardui). It really has been a good year for them.

All in all a little wildlife haven. My garden is much smaller than this and so you would think much less able to attract wildlife?!?! Well check out these images from garden in recent days.

Take a look at this Rose Sawfly (Allantus cinctus) on my rose. This is a different species to the usual yellow bellied Rose Sawflies that I have been following in recent days.

Another visitor to my garden is this House Mouse (Mus musculus) who I found hiding behind our shed. I think he was eating the fallen fruit in the alleyway behind our house. That's enough for now, I'm off to explore somewhere else and see what I can find!

Sawflies emerge!

Happy days! The Rose Sawfly (Arge pagana) in the cocoon hatched today. I opened the jar this morning and seeing that the leaves had gone a bit moldy so left the lid off. The next thing I new was that there was a Rose Sawfly flying around the kitchen. I went back and checked my jar and indeed there was a hole in the cocoon. This chap went in on 26th of July and emerged on the 9th August after 14 days pupating.
So the first thing I did was scoop it up and place it back on its cocoon for some publicity shots and then released it into the wild (my back garden). It could fly right away and made a bee line to the rose bush of its birth. Once there it landed and cleaned its wings (above) it went for a walk around the rose bush, fly occasionally and basked in the sun.

Within a minute another Rose Sawfly arrived! I spotted my one doing this. It can't be egg laying yet so it must be the laying of chemical messengers to potential mates. They grow up so fast!
One last thing of note, it turns out that I got the species wrong before. This is Arge pagana.

August reds arrive

In June nature was white. In July I think nature is blue. In August nature is red. Don't believe me? Check out these recent pictures.
The Dog Rose (Rosa canina) is showing us its fruit, these bright red rose hips look good enough to eat.
Some of the fields are a blaze with this, the Common poppy (Papaver rhoeas).
Here is a sign of the coming autumn, orange berries on the Lords and Ladies (Arum maculatum) plant. Believe me now?

Following blackberry grubs

Raspberry Beetle larvae (Byturus tomentosus) in your blackberries is never a pleasant thing. Down at Watermead the blackberry season has just started. The wildlife down there enjoy the seasonal bounty as much as humans do. Alongside the many birds there is a fantastic variety of insect life and it is the Raspberry Beetle that most enjoys the blackberries. In fact after selecting a few blackberries to make into a crumble we found that once again, our scrump was infested with a type of small caterpillar.
After rinsing the fruit I noticed that our washing up bowl contained eight to ten of the poor little things swimming about. So I carefully fished them out with a teaspoon and pored them and the water onto a piece of kitchen towel to separate the caterpillar from the water. Then I carefully brushed them into a jar containing a few blackberries.
So, granted, it is a little bit disgusting to sit and watch these things wriggle like maggots all over something that I would otherwise eat. As part of a biological study however, this is really interesting. At some point they will have to turn into beetles. How do they do this? Nobody knows and more importantly nobody has ever taken a photo of one in undergoing metamorphosis. You will just have to wait and see what happens.

Fledglings in the garden


My garden has seen some activity recently. A Robin (Erithacus rubecula) appeared one day and had a look around. Soon the robin was back, again and again. Gaining in boldness the Robin explored all the corners of the garden and being satisfied that it was safe and that there could be no sneak attack from a predator, brought a pair of fledglings down (as in the picture above). These baby Robins are just so cute! Mum (below) is busy stuffing them with grubs (including all the remaining Sawfly grubs on the rose). In fact she has become increasingly bold and will now happily root around in the garden just feet from you.

Recently I decided to give next doors hedge a good haircut. I say haircut, it was perhaps more like a number 2 in barbers terms. Anyway, whilst doing so I disturbed a few Large yellow underwing moths (Noctua pronuba, pictured below). In a flash of yellow they would take flight and be away. On one occasion whilst still within the circle made by my hedge cutter wielding arms a moth flew up. Out of nowhere Mrs Robin darted through, avoided the chainsaw wielding fool and caught the moth in mid air, mere inches from the end of my nose. It was spectacular if not a little startling for a man in my position i.e. at the top of a ladder with a heavy duty electric tree murdering machine in my hands. Yet again it seems nature is just jumping out at me!

Barkby Holt, a new stomping ground

I've been looking at it on the map for quite a while wondering what it was like. Barkby Holt appears as a large slab of woodland surrounded by agricultural land. What interesting things would we find if we went there? I didn't know, so we decided to go.


Progress was difficult but we got as far as we could, all things considered, so we got as far as the entrance to the wood and had to turn back. Standing there at the entrance we got a glimpse of some of the treasures within. This is my species list so far for Barkby Holt.


Butterflies and moths
Painted Lady - Vanessa cardui
Holy Blue - Celastrina argiolus
Common Pyralid Moth - Udea lutealis

Insects
Ground beetle - Harpalus sp



Lets take a closer look then.


This, believe it or not, is the first Painted Lady (Vanessa cardui) I have ever seen. Surprising since they are quite common. This year is supposed to be a bumper year for this creature but so far, I have not seen any. This creature has flown from the deserts of Africa to feed on our thistles. They must be good thistles!This is the first Holy Blue (Celastrina argiolus) that I have ever seen, so it really was a special occasion. The photo does not do it justice but the inside of its wings were a lovely vivid blue with dark black tips. Lovely.


I needed help identifying this one. It is a Common Pyralid Moth (Udea lutealis). I found it in the meadows feasting off the ragwort flowers. Its wings have pleats like a roll neck jumper. The final thing I noted is the menacing predator below. If you were a little creature you would run if you saw this coming. It is a Ground beetle (Harpalus sp) and I must say one of the best photos of one I have ever taken.
