It’s been a long time since I’ve updated this blog – everything interesting I’ve seen recently has been far from Grantham, and usually in the dark as bat surveys have filled most of my time! So expect some bat related posts in the near future…
To get going again; this post is just a few photographs from a walk along Grantham Canal and around Denton Reservoir on a sunny, dew-damp September morning. A little bit of everything! It’s sad to see so many of the wildflowers going over, how can autumn be upon us while we’re still waiting for summer to begin? Still, a few flowers are still hanging on:
Black knapweed (Centaura nigra) is a favourite with the bees and butterflies and a few are still in flower.
Yarrow (Achillea millefolium) is a native which you may even have growing in your lawn, or one of the ornamental coloured varieties in the flowerbeds. Look out for the feathery fronds of leaves beneath.
There are several hawkbit (Leontodon spp.) species – I believe this one is the appropriately named autumn hawkbit. They are in the same family as the dandelion – the daisy or compositae family – but are a much finer, more delicate species.
Ever-ebullient ragwort (Senecio jacobaea). There seems to be a fair bit of debate at the moment on whether it really is dangerous for livestock, but it’s another brilliant species for invertebrates. Look out for the yellow-and-black striped caterpillars of the cinnabar moth in July and August.
Creeping thistle (Cirsium arvense) is another species with a long flowering season.
Rosebay willowherb (Epilobium angustifolium) flowers later in the season and brightens up the countryside, especially around water. This photo was taken beside Denton Reservoir.
Harebell (Campanula rotundifolia) is a species I was not expecting to encounter – this was growing within a sheep-grazed field to the south of Denton. It is a delicate flower often found in more dry, nutrient poor grasslands and heathland, Sherwood forest is a good area to spot them. A welcome addition to the day!
The fields look as though they are on fire from a distance as clouds of dust rise like smoke from the combines. With the crops gone and the stubble remaining, it’s a good chance to look for a few arable plants. There are a number of species which are well adapted to arable conditions and are growing rather rarer these days thanks to the intensification of agriculture. Below are photographs of scentless mayweed (Tripleurospermum inodorum) and common poppy (Papaver rhoeas) – not rare but attractive, I especially love the texture of the poppy flower!
I spotted a fair few birds within the hedgerows and arable margins, it’s getting to the time of year when large numbers descend on the feast of berries which are ripening. Plenty of blackbirds along with mixed-tit flocks, yellowhammers, chaffinches and an attendant kestrel. This stretch of farmland is a great spot for fieldfares and redwings when then arrive for the winter too.
The last few butterflies were still floating and resting in patches of sunlight; red admirals, comma’s and speckled wood all in evidence. Below is a comma (Polygonia c-album) sunning itself on a bunch of ripening blackberries!
Dragonflies and damsel-flies were spaced out along the edge of the reservoir, the dragonflies jealously guarding their patches. This was my first attempt at a dragonfly in flight, I’m quite pleased with it! I am not 100% confident on the ID but this is certainly a hawker dragonfly, probably a southern hawker (Aeshna affinis) judging by the amount of green on the thorax but please feel free to set me straight if it’s a common!
