In fact I was sidetracked before even entering the woodland. At the end of Browns Road, at SP554625, stands a line of about ten poplars. they are Balsam Poplars, Populus balsamifera, or a closely related species. Whatever they were, the air was fragrant with the lovely scent of balsam resin.
Many of the leaves bore regular pale spots. I suspect this is not a disease but a natural feature of the species. Certainly I have observed it at other sites.

Whatever the species it was proving extremely popular (sorry, no pun intended) with beetles. Dozens of the leaf beetle, Phratora laticollis, were present, many of them mating. Although this beetle is occasionally found on willows it is overwhelmingly a poplar specialist.
This hoverfly, Syrphus ribesii, was loafing on a leaf. Ribes is, of course, the gooseberry/blackcurrant genus but this insect appears to have no particular association with these plants.

Also present - and of more interest - were two other hoverfly species: Xylota segnis and this smart female Dasysyphus albostriatus. Neither is rare but may be new records for this area.
And so on to Kentle Wood. With a strong wind blowing I worked at ground level investigating grass tussocks. Again the species recorded are of no general interest.

the far commoner Bright-line Brown-eye, Lacanobia oleracea, a pest species often found in gardens. (I always have to double-check the name!)
Click beetles were very common in this situation too. Their common name comes from the fact that they are to leap in the air while on their backs, making a distinct clicking sound. Their larvae, known as wireworms, are a pest of agricultural crops. I examined four specimens and all proved to be the Dusky Wireworm Beetle, Agriotes obscurus. Rather disappointing as this had already been recorded from the site.
The survey is going well. Before today I had recorded 17 species of flowering plant (ignoring those trees planted to create the woodland), 2 fungi (not really my thing) and 109 invertebrates including 21 species of spider, 23 beetle species and 30 flies. But I now have a heavy workload to deal with today's findings.
