Ladybird Larvae Like Lime Lice

Following my chance encounter with Harlequin Ladybirds hatching, the subject of my last post, I have quickly found a new tunnel of learning to run down. I returned to the Lime tree where I had previously discovered both adult Ladybirds and pupae, determined to expand my survey. This time I found that every single one of the Lime trees on Tyntesfield's lower drive was hosting many hundreds, probably thousands of Ladybirds. With a minimal amount of extra scrutiny I was able to find not only adults and pupae, but also lots of larvae still active. 

As I was taking pictures of a larva on a leaf I became aware of a host of smaller residents - lots of fast moving tiny termite like creatures. These I now know to be Barkflies, a relatively recent (2003) renaming from Barklice in an attempt to improve their image. It certainly worked for me, I found watching them compelling as they whizzed around and interacted with one another in their micro-colony. They are the outdoor version of Booklice, not regarded as pests and, I assume, a tasty snack for a voracious Ladybird larva.

On today's gloriously sunny morning I went out to photograph the scenery, but found myself drawn back to the Ladybird Limes. The last couple of pictures show several stages of the transition from larva to adult. Next for me is to find out how long the process takes. I bought a leafed twig home with me several days ago with a couple of larvae on, but they have yet to start the transition. Camera shy perhaps.

Part of the joy of writing this blog is researching the things I observe and the glorious fact every creature has a fanbase. Here is a link for the Biological Records Centre: Barkfly subsection. It is a fine, fine thing and I give my respect and gratitude.

A whole colony of Barkflies were living on this single leaf

A winged Barkfly, either an adult of those above or possibly a different species.

Strangely inquisitive for 3mm long insects, this was possibly the first time they'd encountered a human. Note the filaments of webbing made by the Barkfly to create a protective net over their colony.

Killer Harlequin Craze

I took a gaggle of five and six year olds on a Tyntesfield nature ramble this weekend. I was supposed to be the knowledgable one, but as ever it was new discoveries that struck me most. On the leaves at the base of a single Lime tree on the lower drive, we discovered hundreds and hundreds of Ladybird larvae in their pupal cases. Some had hatched and left empty cases, but many remained sealed. One adult ladybird was yellow and looked a lot like a pine nut. This was one that had just hatched, the spots coming through some time later.

I'd been wanting to find some pupae to film and photograph. Without finding one in the summer, I've now discovered legion. I will check the other trees along the drive to see if they are carrying the same burden. These are Harlequin ladybirds, non-native and apparently flourishing. My reference sources tell me Ladybirds emerge as adults in August before hibernating from autumn through the winter. The fact the Harlequins are hatching now in mid October in large numbers, would appear to mean they have a longer feeding and breeding season. I can't compare this to our native species without the facts at my disposal, but if their prey species (aphids and other bugs including ladybirds) are living longer due to milder autumns, then the Harlequins would appear to be making the most of it.

I took a couple of leaves home with pupae on and took the photographs below. The adult ladybird was the one seen earlier when yellow. You can see a translucence to its wing cases which I imagine disappears as it hardens and matures.

Before the ladybird pictures are some floral entries and a Cranefly unhappily stuck in a spider web. I find the Ivy flowers spectacular, modest from a distance, but highly impressive close up and a valuable source of food for many insects. This bush was a-buzz with bees, hornets and a very few wasps. To my personal vexation, someone from the National Trust had hung wasp traps from the bush. I would argue that putting traps on a natural food source is not a particularly smart way of keeping wasps away from your nearby cafe.

Dropping the Hawker kids off at the pool

October is here and dragonflies are still in the air. The Southern Hawkers below were seen at the Home Farm pond. The bottom picture is a female who came to the pond on an egg laying mission. This particular dragonfly species lay eggs in vegetation above the water surface, or on my shoe as happened with this particular individual. When I get on with digging my own pond I shall plant said shoe in the margins in the hope the eggs hatch next spring.

Shortened Expectations

Cruelly I am now spending most of my days in a small dark room. I am feeling very nature deprived, though the fact I'm big enough to not be eaten by a spider is cause for some comfort when I do get some time outdoors.

Hop No More

Like Monet, my eyesight is deteriorating, so here's an impression of a good photo

Hawkers and Hangers

My dragonfly education continues and I'm now able to identify different species of Hawker dragonflies in the skies of Tyntesfield. At the same time I am compelled to accept that the Emperors, flying since June, have now hung up their wings for good.

Embracing death and the cycle of life, I've now developed an interest in 'things found hanging in spider webs', not least because they are relatively easy to photograph and intriguingly mysterious when viewed in close up.

Invasion Of The Lilly Snatchers

Last week I witnessed a strange phenomenon at the kitchen garden pond. The entire water surface was covered in a dusting of white flecks. It seemed to me that these were hatching flies of some kind, but it was not obvious what they were to the naked eye (not to my declining ones anyway). I returned with a macro lens to discover a flotsamic mess of drowning insects and shed skins. Where any plant protruded from the water it was covered in survivors as were the lilly pads and their flowers. This was, I was to discover, an explosion of Water Lilly Aphids.

As I tried to photograph these 1-3mm long sap suckers I began to notice all the predators in attendance. Lots of pond skaters and backswimmers, but more to my amazement was witnessing a tiny parasitic wasp come and inject her egg(s) into a hapless aphid (who was perhaps at the time wondering how it had had the good fortune to avoid the drowning fate of so many of its siblings).

On reviewing my photos I then saw more than one aphid carrying what looked like fly eggs on their backs. These I now believe to be hover fly eggs. I can't imagine the aphids have a particularly long life, so both wasp and fly larvae must develop very quickly, perhaps moving onto a secondary host if they themselves outlive the aphid?

Anyway, the moral of the ongoing story is that just because there are no fish in a pond it doesn't mean nothing is going on.

Emperors Go Wild

Released from my self imposed watching duties in the walled kitchen garden, yesterday I took a freedom tour to the other ponds on the Tyntesfield Estate. I've lived on the estate for over a decade, but I never knew of the existence of Warren Pond until a National Trust estate guide told me of it. I'm slightly ashamed about this as it's not particularly hidden, in fact it even has a sign post. 

Anyway, it was pond love at first sight. I watched Broad-bodied chasers duelling, mating and egg laying and was briefly visited by a Banded Demoiselle, to me the most seductive of all the dragonfly family that I have so far encountered. A year ago I didn't know what a Broad-bodied chaser was, I'm now familiar with half a dozen or so species, so my journey of discovery has really only just begun.

Having been tantalised at the kitchen garden pond, I determined to try and catch some photos of dragonflies in flight. I took about 200 shots with my very modest camera without great success, but I did definitely improve with both camera operation and fieldcraft.

Later I moved on to another pond near to Home Farm and the 'scrotum tree' as it's colloquially known (to me at least). Here I had the joyous discovery of an Emperor Dragonfly male hawking back and forth across the pond. He stopped briefly for a generous portrait and then continued on the wing, mating with a visiting female who then withdrew to the pond margins to lay her eggs. Another 200 or so photos and a milestone in a my photography as I managed to get him in flight AND in focus.
