I was at Blashford Lakes Nature Reserve today after a couple of days off. We had a volunteer work party in the morning but before we started I checked through the moth trap, although the catch was quiet good there was nothing too surprising, although I was pleased to see my first peach blossom of the year, no picture though as it flew off. There were several hawk-moths including a group of three elephant hawk-moth on one egg box.
There were also a few species of prominents including a pale prominent, they all get their name from the small raised point on the folded wing, presumably an adaptation to break up their outline and make them look less like moths. For a moth, not looking like a moth is very useful as birds love to eat moths, so lots of moths either hide away or just try to look not like moths. The pale prominent does this rather well.
Our volunteer tasks were giving the outside of the Education Centre a was down and having a clear-out of the tool store, both much needed tasks, if not exactly conservation work. At least we should be able to find most of the tools and equipment now and the building does look a lot smarter for a wash.
I checked the hemlock water dropwort around the centre pond at lunchtime for visiting insects, the flowers are a very good nectar source. There were lots of hoverflies and a few beetles including a wasp beetle, a yellow-and-black longhorn beetle and a red-headed cardinal beetle.
What’s in My Meadow Today?
By the time I got home most of the meadow in my garden was in shade, but it was still making its presence felt. The grasses are flowering and their pollen is blowing in the wind as every hayfever sufferer will know. Grasses do not rely on insects to carry their pollen from one flower to another to achieve fertilisation, they just release huge clouds of pollen into the air to be carried to another flower. This saves on the need to produce nectar as an inducement to insects, but does mean that a lot of pollen has to be produced.
Many trees use the same method, resulting in allergic reactions for many in spring. Pollen deposited in peat and similar wet habitats has allowed us to look back in time and work out what the dominant vegetation cover was in the distant past. It turns out that although there was rapid colonisation of the UK by tree after the end of the last Ice Age the nature of the cover changed over time. One tree now generally rare, the small-leaved lime, was abundant at one time and it turns out that elm have seen several rises and falls in abundance, perhaps indicating previous outbreaks of “Dutch” elm disease.
The tiny garden pond does not have many plants, but one it does have is lesser reedmace and it is now flowering and also sheds pollen into the wind, the pollen is produced by the male part of the plant, which here is the upper part of the flowering stem.
