Morning fungus foray in action (Photo by Rupert Wilson)
UK Fungus Day was marked by excellent weather for seeing and collecting fungi. The group walked through the Wilderness on the morning foray and then in to central campus for the afternoon foray. The group consisted of Thames Valley Fungi Group members, several University alumni and a group of MSc Plant Diversity students as well as School of Biological Sciences staff.
It was a cool, clear night, and 8am found the Harris Garden wreathed in mist and drenched with dew. Would any moths have found their way into our light traps in these conditions?
The Harris Garden gate.
Trap still shining on at 8am. This is a portable trap using an 8W actinic bulb and a 12V car battery. Moths are attracted to the light, hit the vanes which surround it and drop through a funnel into the body of the trap (a plastic bucket!)
Further to Alastair’s post, whilst it is probably too late to put on an official event I will have two light traps running in the Harris Garden overnight. All welcome to join me from 8am tomorrow to open them and see what we catch.
This would also be a good moment to point out that Reading is competing in a ‘University Moth Challenge’, organised and supported by A Focus On Nature and Butterfly Conservation. Similar to the bird challenge (in which we did very well) there are a number of categories, including number of species and individuals recorded and number of participants. The competition is very much aimed at students, so we’re looking for as many as are interested to get involved.
Over the next two nights the UK will be aflutter with moth enthusiasts looking to see what is out and about. UK Moth Night aims to celebrate British moth recording activity and highlight this to the public. News coverage has been good. On Today this morning I heard the advice to mix beer, treacle and sugar but there seem to be almost as many recipes as there are moth spotters!

A new hybrid for campus. Image by D. Morris
June saw the publication of a hybrid flora of Britain and Ireland. The book is authored by the luminaries of British botany Clive Stace, Chris Preston and David Pearman, with contributions from many botanists whose expertise extends into the esoteric world of plant hybrids, and is a mine of information. It has coincided with my increasing awareness and interest in plant hybrids, and I thought I’d share a hybrid I recently found on campus.
The image to the left shows the plant in situ. Can you spot what drew may attention to it? Why is it not just ordinary cinquefoil?
I had the distinct honour of adding a butterfly to the campus species list this week, in the shape of a rather smart White Letter Hairstreak. New moths come along on a near weekly basis – hardly surprising since we’ve recorded barely 1/10th of the UK fauna – but butterflies are far less diverse and consequently new site records are much more difficult to come by. It was in the small clearing at the heart of the Wilderness, resting low down in rough grass at about 8:30 in the morning on Wednesday 23rd.
Every one loves bees these days and pretty much everyone loves bee orchids (Ophrys apifera) too!
The University of Reading campus is no exception and there is a small population flourishing in purposefully unmown grass opposite the Hopkins Building and outside the RSSL Building.
You can’t miss it but step tread carefully lest you trample a spike or two, as has already happened where eager plant hunters have stepped on the long grass (and a hidden bee orchid) in their eagerness to get a closer look at these fine and very beautiful wild flowers.
The Bee orchids are at their best in second half of June so please admire them, it may take your eyes a while to adjust and find these rather delicate plants amongst the grasses and other flowers but its worth the effort but please keep to the mown edges and do not tread anywhere on the long grass!
There is no need to be alarmed the Hornet Hoverfly (Volucella zonaria) is a harmless species. Although I will admit, in its outwards appearance, if you have never seen one before or happen to see it out of the corner of your eye, it is an excellent hornet Batesian mimic and will get your attention rapidly! The species mimics the colours and the size of the defended hornet, with its potent sting, to avoid predation. This species is off interest as for one its large and easily spotted (our largest species of hoverfly) and two it has only colonised the UK since 1940 and has an interesting biology. This species was seen on campus on the 20/August/2012, no doubt obtaining salts from freshly dug compost. Continue reading
Slender field speedwell
Like the Common field speedwell (Veronica persica), the Slender speedwell (Veronica filiformis) has relatively large bright, blue and white flowers, each held at the end of a long stalk, well clear of the leaves.
The Slender speedwell can occur on bare patches of soil but is most often seen in lawns. Its prostrate stems enable it to continue to grow despite regular mowing and it seems to be able to hold its own even when crowded by grass tillers.
The easiest way to separate it from the similarly large-flowered Common field speedwell is to look at the shape of the leaves. The Common field speedwell has a distinct point at the leaf tip, whereas the Slender speedwell has a rounded tip to the leaf.
This afternoon I was out enjoying the sunshine and doing a spot of fly-catching in the meadows near the meteorology field station. At about half past 3, I thought I heard – or perhaps imagined – the jug-jug-jug-jug phase of a nightingale’s song. A few minutes later and it sang again, a longer phrase: I was not suffering from sunstroke induced hallucinations but was indeed hearing a nightingale sing, from dense vegetation down near the lake.
It was still singing earlier this evening, thanks to Peter Gipson for the update. It’s late in the year now for a nightingale to be setting up territory, so this is probably either a late passage bird or a wanderer that has been displaced from one of the nearby nightingale hotspots at Theale to the west and Dinton Pastures to the east. Well worth hearing whilst it is with is. It was near the main bridge this afternoon and a bit further south this evening, sticking to the east side of the lake. Directions are, in any case, hardly necessary: if it does sing whilst you are out searching it will immediately give its location away!
