Macro photography in the garden



One of the many things I love about macro photography is that there are so many wonderful insects to be found quite literally right at home just in the garden. The following photos are all images I’ve taken in the last couple of weeks when I’ve had a few spare moments and the sun has been shining. Macro photography in the garden also of course has the additional bonus of avoiding the attentions of concerned passers-by (or their curious dogs!) wondering why on earth you’re scrabbling around in the undergrowth or lying on the ground!!! (I have warned our neighbour not to be concerned should he spot me lying face down in the grass!)

Another bonus of being in the comfort of my own garden, I’ve been able to while away some time messing around trying to capture photographs of insects in flight. I was quite pleased with some of the results I got from taking (many!) images of honeybees visiting a clump of grape hyacinth flowers by varying the camera settings as well as swapping between auto and manual focus (I think the latter works better for flying insects!).

Also catching my attention have been the many hoverflies guarding their respective territories – a fun if sometimes frustrating challenge to quickly get them in focus as they hover in front of you, only to have them zoom away the moment you press the shutter! The ones I have been particularly trying to capture are the species Eristalis pertinax, distinctive by their yellow front and middle legs, they are also one of the earliest of the hoverflies to emerge in the spring, with the males characteristically defending their ‘patch’. These are the ones which will often hover at head height giving you the once over (or at least so it seems!). It can be a little disconcerting when they do this but they are entirely harmless.

Several other types of hoverfly have also been visiting the garden, the couple below having been found just enjoying the sun on different garden plants. (I've tried my best with IDs but as ever, please let me know if they're incorrect....)

Similar but different - Syrphus torvus (left) and Epistrophe eligans, both female




Speckled Wood butterfly
As spring progresses more types of insects have been emerging by the day. Just in the last week we have had three new species of butterfly visiting the garden; Orange-tip, Holly Blue and Speckled Wood. The Orange-tip and Holly Blue  butterflies will have spent the winter in their chrysalis form, emerging as adults when conditions are favourable. Speckled Wood butterflies can spend the winter as either a chrysalis or caterpillar. 

It has been great to see these spring butterflies, in what will be their first broods of the season, though the only one which stopped long enough for me to take a photo was a Speckled Wood (fortunately these butterflies don't seem to be particularly camera-shy!).


Lily beetle

Another beautiful find, though really not a 'gardener's friend' was a lily beetle (the adults, but also their larvae especially love to munch their way through lilies, causing a lot of damage). 

This one wasn't on a lily so I wasn't concerned about any plants, until it did a purple poo.... (Yes I ended up with a photo of that too though it wasn't actually intentional!) Then the penny dropped that s/he had been busily eating my husband's new Snake's head fritillary flowers.

(Apparently fritillary flowers are the next best thing to lilies where these pretty little beetles are concerned -the beetle was safely relocated elsewhere!)

 






Harlequin ladybird

Also found on the Snake's head fritillaries was a Harlequin ladybird - the 'villain of the piece' where ladybirds in the UK are concerned. This pretty but invasive species arrived here in 2004 and out-competes our native ladybirds having a wider food and habitat range as well as a longer reproductive period.

Harlequin ladybirds have quite an unfussy diet - whereas they feed most commonly on aphids, when these are scarce they will also eat other ladybird eggs, larvae and pupae, as well as butterfly and moth eggs and caterpillars. 

There is lots more information about Harlequin ladybirds such as how to recognise them (their patterns are very varied), their spread and current distribution and also how to submit sightings of them on the Harlequin Ladybird survey website.
 



Of the bumblebees there was one unfortunate individual, a white-tailed bumblebee queen, that I noticed motoring across the garden lawn on foot. When I looked more closely it became clear that she couldn't actually fly, with the wings on the right side of her body being completely immobile (in the photos you can see the smaller wing at a strange angle). She was managing surprisingly well, determinedly heading towards a patch of flowers, then climbing the stalks to reach the flowers, though I couldn't help but feel a little saddened that by whatever means her fate had been sealed.

Numerous types of solitary bees have been visiting flowers in the garden - they tend to be quite small and often skittish in their flight so can easily be mistaken for flies - it's worth having a closer look to see if it's a tiny bee that you're looking at. Trying to identify what type they are though is a different matter entirely...  


Solitary bee - Osmia sp?




A slightly surprising find considering the garden isn’t particularly close to any bodies of water and I'm not aware of neighbours with ponds nearby was a small Mayfly, only 2cms long including the ‘tails’.  I’m not sure which type this is, though with many types of mayfly in the UK, several of which need microscopic examination to differentiate, it is often very difficult to know for certain. (I’d be interested to hear from anyone who knows the ID of this one.)

Sutton at Easter



Duclair duck
Black Muscovy duck
Heading over to Sutton reservoir again in beautiful sunny weather in Easter week, I was initially greeted (as is usual here) by the resident selection of feral ducks. Mostly these are clearly varieties of domestic Mallard, being quite different in plumage, but also considerably larger than regular wild Mallards. One that had joined the mix which I haven’t noticed before was a different type of duck altogether – a black Muscovy duck. Not being at all familiar with domestic duck breeds it’s an interesting challenge to try and work out what they are (do let me know if I’m incorrect on their IDs!), but I photographed what I think are a group of three Campbells, one Duclair (of two present), and then the black Muscovy, possibly female as she seemed quite small for this kind of duck. 

An interesting website I came across a while ago while trying to work out whether ducks I'd seen were domestic varieties of Mallard, hybrids, or some other unusual colour variation such as leucism (or something else entirely!) can be found here. The unfortunate term previously coined of 'manky mallard' isn't meant unkindly here, and the site has lots of great examples of the weird and wonderful variations of Mallard that may be spotted when out and about nature watching (though judging by some of the comments, perhaps some of the IDs suggested on the website may be up for debate!!!).  


A trio of trouble - boisterous Campbell ducks!










A different kind of challenge was that of trying to photograph some of the bumblebees. The reservoir is surrounded by Willow trees, and the catkins were proving as popular a draw as ever for various bees, butterflies and other insects. Getting in amongst them, I attempted to photograph some of the bees in flight, queen White-tailed and Tree bumblebees being the ones I spotted here on this occasion.

Barren strawberry flowers
Peacock and Small Tortoiseshell butterflies also fluttered among the branches laden with catkins, and also visited the flowers of Lesser Celandine, now carpeting the sunny banks as well as covering the ground in some of the more shaded pockets of woodland. 

Pink Purslane flowers
Other wildflowers in bloom included those of Barren Strawberry, so called because despite looking very similar to wild strawberry plants, they don't bear strawberries (sadly!), Wood Anemone, and Pink Purslane. This latter flower is native to western North America and also Siberia but having been introduced to the UK in the 1700s is now widespread here. 

Wonderful to see were clumps of pale yellow Wild Primrose (I've yet to see the pink variety that can also occur in the wild), one of our earliest spring flowers, it's name deriving from the Latin prima rosa meaning 'first rose', although it isn't a member of the rose family.

Something I haven’t seen for many years which I spotted next to the path was a type of puffball fungus, about 6cms across. I resisted the temptation to give it a good squeeze to release the spores in a cloud of brown smokiness, something I remember doing as a kid whenever I found one! Perhaps next time I shall do, just for old times’ sake!

Easter butterflies and other insects


With some beautiful weather over the Easter holidays, it has been wonderful to see the local environment transforming, with ever more wildflowers blooming such as wild primrose, wood anemone and forget-me-not to name a few, trees gradually coming into leaf, and accordingly insects emerging from their long winter slumbers. Having taken a few days off work over the Easter holidays and with the good fortune of some wonderful weather coinciding, this and the next few posts will be a catch up on several visits made to local spots where I enjoy watching wildlife in the past week (in between also trying to repaint a garden summerhouse!), starting with the Quinta arboretum and also the Quinta wildlife trust reserve in Swettenham which is accessed from it.

I headed over to the arboretum on Easter Sunday and Monday with the hope that the fine warm weather would bring out the butterflies. I certainly wasn’t disappointed, and in these visits saw a 'full house' of the UK butterflies that overwinter as adults. A beautifully brightly coloured male Brimstone I only saw in flight – they are strong fliers and I couldn’t follow him to wherever he might have landed. Commas, Small Tortoiseshells and Peacocks were present, not in huge numbers, but wonderful to see again. Also, enjoying the flowers of a Pieris was a Red Admiral. These butterflies are generally considered to be migrants to our shores, with large numbers arriving from central Europe in May and June, however there is increasing evidence that some are managing to survive hibernation through our milder winters - it may be that being here in early April means that this was one of them.

Willow catkins are magnets to insects at this time of year, so I spent a while watching and photographing the visitors at a couple of willow trees where the catkins were full of pollen, and also many branches were low enough to get close to some of their insect visitors. This was where I saw Comma and Peacock butterflies, also enjoying the catkins were a selection of flies including prettily coloured greenbottles and various hoverflies. 
 
On a previous recent visit to the arboretum, of the bumblebees, I had just seen Tree and Buff-tailed, this time in addition there were Early and White-tailed bumblebees. Lots of tiny solitary bees of different Andrena species were also making the most of this pollen bounty.

High rise living - Grove snail 10 feet up!
Solitary bee (Andrena haemorrhoa?)
Looking a little out of place at nearly 10 feet up a tree was a snail (a Grove snail I think - Cepaea nemoralis). Also enjoying the catkins was a Peacock butterfly - this one was visiting the uppermost catkins, but would also periodically fly down to ground level to bask in the sun where I was able to take a few more photos from within a foot or so. Unsurprisingly, sudden movements will make a butterfly take flight, but with care to avoid this and importantly to avoid casting a shadow over them it is possible to get quite close without frightening them away. This individual's wings were a little tatty around the edges, but for a butterfly that has come out of hibernation I thought looked in pretty good condition. I also checked on the chrysalis of what I think is a Large White butterfly that I'd spotted a few weeks ago, and it was still there looking entirely unchanged - it can't be much longer now until the adult butterfly emerges!

Insects love to bask in the sun, and a smooth warm surface like a bench, post, tree trunk etc, is a great place to find interesting insects. Sharing a bench with a load of flies might not be everyone's idea of fun but armed with a macro lens on the camera I was kept amused for a [worrying?] length of time. Before getting a macro lens, I hadn't paid much attention to hoverflies, but many of them are really quite beautiful, and in some cases (like Rhingia species) interestingly shaped. I'm still very much a novice when it comes to attempts at identifying hoverflies, but for anyone interested in learning more, an excellent book on the subject is 'Britain's Hoverflies, an introduction to the hoverflies of Britain' by Stuart Ball and Roger Morris. Reports can also be submitted to the Hoverfly Recording scheme which is administered by the authors.

Male hoverfly - Syrphus torvus
One interesting feature of hoverflies is that the males and females of most species can be told about by the spacing of their eyes - the males' eyes meet at the top of their heads, whereas the eyes of females are spaced apart. You can see this in the photos below I took of a male and female Eristalis pertinax whilst sharing a bench with them!

Checking back at the Pieris again on my way out, I found a tiny ladybird I didn't recognise, about 3-4 mm long. From looking at the UK ladybird survey website, I think this is another colour variation of a 10-spot ladybird, quite different from the 10-spot seen previously which had a ground colour of orange and more clearly defined black spots - these colour variations all adding to the fun of trying to identify these tiny creatures I find on my forays into their micro worlds!
