The signs are there

We have rain forecast for the next few days, so I took the opportunity to see what signs of spring I could find.

7-Spot Ladybirds hibernate as adults, so in theory they can be seen at any month of the year if the weather is warm enough. But I like to think that the first sighting of the year is a sign of things to come:

Many plants are still in their purely vegetative state, but quite a few are making flower buds or new growth. I always consider Barren Strawberry to be the first true flowering plant in each year. True, Celandines will always flower first, but since they can flower any time from November onwards, the Barren Strawberry is my 'first flower' in any given year:

The plant at top right of that shot is Germander Speedwell which had a very good year last year:

The lowest stem in that shot shows the diagnostic paired lines of hairs that run along the stem.

Bush Vetch is also pushing through the dead fronds of last year's Male Fern:

It will be another 4 months before Slender St. John's Wort is in flower, but already the new growth is forming:

I cropped this shot of Opposite-leaved Golden Saxifrage to show the rear wall of the ditch covered in liverworts and mosses:

The main liverwort is Conocephalum conicum ('Snakeskin Liverwort') and the tiny moss is Plagiomnium undulatum.

A few years ago, one of the few local areas to have wild Reedmace was excavated to see if it would be suitable for building a house (it isn't!). Most of the Reedmace disappeared, but some has now made a recovery:

Reedmace - Typha latifolia
Typha is the sole host family for many insects, including some moths and hoverflies. I examined quite a few specimens of the Reedmace for any signs of those species, but none were found. I wonder how long it will take for them to return (if they ever do).

No time is ever wasted in nature: the leaves of Lesser Celandine are hardly full-grown and already the fungal rust Puccinia ranunculi has taken hold.

Last year there seemed to be a very wide-ranging absence of fresh mines of the micromoth Stigmella aurella from its main foodplant, Bramble, and I certainly found very few.  So it's good to see a good number of fresh mines (fresh mines are white, whereas old mines from previous years are brown) on the host plant this year:
Mines of the micromoth Stigmella aurella
There are 4 mines on that leaf, all of which appear to have grown to full size. I'm always entertained by the way the mines progress without falling out of the edge of the leaf and also how they seem to detect other mines and take avoiding action before they intersect them (or their own!), especially when older.

Sunny August

In this shot I tried to show the extensive Fuchsia hedging that paints much of western Ireland red at the moment, but the very bright sunshine made a decent shot very tricky.

Note the very straight road stretching all the way westwards to the horizon. I had always thought that these long straight roads must be Roman roads, but the Romans never got this far, and the roads are known as 'Famine roads'.

The white umbellifer plants at the front of the shot are Angelica.

Many of the wasps that can be seen slowly crawling over umbellifers at the moment are males:

Male Vespula rufa
Vespula rufa can be identified by a combination of features including the red areas on the abdomen, facial markings and stripes on the thorax.

This Chloromyia formosa soldier fly was happily nectaring on the Angelica......

until a Tenthredo sp. sawfly decided it would make a good meal and jumped on it:

Even at 1/120th of a second, the fly is just a blur.

It's not only the flowers of Angelica that attract insects: leaf-miners are also present. Phytomyza angelicastri is one of two species that I find locally:

The Hawthorn parasite Taphrina crataegi clearly has some special habitat requirements. This is the only tree that I have found to be infected on my patch:

I have also found it in one location in Northern Ireland, and in each case the tree overhangs lying water, but I know of many Hawthorns in similar situations that are unaffected, so it must be something more subtle.

As I was searching along a verge, a shadow passed over me and I looked up expecting to see a bird, but it turned out to be a huge Common Hawker dragonfly which was hunting along the same verge. I followed it for a while and it eventually rested on a Willow, so I managed to squeeze in a few distant shots:

And nearby I saw a Common Darter landing on a grass stem. She tolerated me for quite a while before flying off:

Slender St. John's Wort is my favourite flower, so I made an artistic crop of this pair:

Sunniest day of the year

After early mist lifted, we had a clear blue sky and 22 degrees: we might get 2 days like this a year. So off up to the forestry to see what was going on.

Eristalis Hoverflies are still in evidence, and the males were holding station on the pathway:


Manual focus on those!

This little Braconid wasp was one of many looking over and under Willow leaves. They're probably still looking for the last of the sawfly larvae to parasitise:


Those of you who have been following my travels will know exactly how I feel about Slender St. John's Wort. The specific name 'pulchrum' shows what the people who named this in the 1700's thought of it, too:

This tiny (3 mm) Chrysomelid beetle was posed adjacent to next year's Willow leaf bud:


And finally - just to convince ourselves that we actually are in October - a solitary specimen of the Deceiver, Laccaria laccata:

Moths galore

One of the most common caterpillars on my patch is the Garden Tiger moth: they're all over the higher-level plants. This is the first time I've seen the wonderful adult, however:


The white plume moth is the White Plume Moth - Pterophorus pentadactyla, which feeds on Convolvulus (and is one of the few micromoths with a common name). This is another first for me:

And another new first for me is the Satin Beauty - Deileptenia ribeata, which feeds on Norway Spruce. Unsurprisingly, this is an increasing species:
Just for the record, a July Highflyer:

And to finish off for today, my favourite flower, Slender St. John's Wort:

Playing catch up

In the normal order of things, higher order species tend to prey on lower-order species, so wasps and bees tend to be predators on flies (or members of their own order). The Conopid fly Sicus ferrugineus, however, reverses this trend. These are parasitic on bumblebees, stapling a single egg into the soft underside of the worker's abdomen. This oviposition is said to take place in flight, but I have never seen it happening. Once the bumblebee has been parasitised it tends to change its feeding habits, presumably to the benefit of the fly larva.


Mesembrina meridiana is easily recognisable due to the orange wing base. The name indicates that it is a noon flyer, and that's when I usually see them.


Angelica has flowered and that means plenty of shots of nectaring insects. this is the Tree Wasp - Dolichovespula sylvestris. It has an overall orange feel to the colouration and the antennae bases are yellow. Facial decoration is a single small spot.


This male hoverfly looked unusual, but it consistently keys out to the very common Eristalis pertinax.


Trombidium sp. mites are usually seen scrambling over the base of plants as they search for rotting vegetation. This one was sunning on a grass blade.


Those of you who have been following my websites for a few years will know that this is one of my favourite flowers: Slender St. John's Wort - Hypericum pulchrum. The latin name shows that I'm not alone in that opinion.


This pristine flower of Meadow Buttercup - Ranunculus acris - caught my attention:


Finally for today - Eyebright. That's as far as the id is going.

Exotics in the bog

I'm always amazed by the complexity and beauty of Bog Asphodel. It just seems too exotic to be in a local bog.

The Common Spotted Orchids are very large and numerous this year. I found three on the lawn of our local Health Centre.

One of the most common mosses at the fringe of the bog: Polytrichum commune.


And at the very edge of the bog, my favourite flower: Slender St. John's Wort.
