After yesterday’s attempt at a picture of a flying hoverfly I had to have another go today and I got the chance on my way round to close up at the end of the day. Yesterday’s was a Syrphus species, today’s was Volucella pellucens.
The warm nights are improving things in the moth trap with catches increasing in number and species diversity. The highlight overnight was a very fresh male goat moth.
These extraordinary moths have caterpillars that eat wood by tunnelling into live trees, especially willows. As wood is not very nutritious they take several years to grow to full size.
It is also proving a good year for butterflies, with most species well up on recent years on the transects. Just now the summer brood of comma are very obvious, nectaring on bramble and just perched out in the sunshine.
Dragon and damselflies are also enjoying the warmer summer with good numbers of most species. The only ones that were scarce seem to have been the spring species, possibly because last year’s spring was so poor there were few to hatch this year even though the conditions were good. So far I have failed to add any new species to the reserve list, despite there being several that could wander here, especially from the New Forest. For instance there is the scarce blue-tailed damselfly, which could easily get blown in and is known to wander from breeding sites. It is rather similar to the much commoner blue-tailed damselfly, which may be one reason why we have so far failed to find one.
