30 Days Wild – Day 2 – Hawks and Dragons

Once again a day off at home trying to work in the garden, but the sun was a bit much so productivity was rather low!

However the day started with a look through the moth trap, most of the moths would have been attracted before midnight when it was warmer, but as the minimum was 14 degrees some will have been active throughout. The pick of the catch were a couple of hawk-moths.

Lime hawk caterpillars eat the leaves of lime trees, but also birch. Many hawk-moths are named after the larval foodplant, or at least one of them. The privet hawk-moth caterpillars eat privet, but also lilac and ash, it is our largest resident hawk-moth.

Other moths caught were buff-tip, heart and dart, treble lines, flame shoulder, light brocade and fox moth.

The sun brought a few butterflies out, I saw a male common blue and a female brimstone in the garden during the early afternoon.

The sun also encouraged a fair few hoverflies to feed on flowers in the borders.

Eventually I gave up on the garden and went out for a walk in the New Forest, luckily I live close enough not to need to drive there. The recent wet weather has filled a lot of the small ponds and each one seemed to have a broad-bodied chaser or two.

There were also good numbers of emperor and four-spotted chaser too.

The New Forest is one of the largest areas of semi-natural open space in Southern England, although a “Forest” it has a lot of wide open treeless areas. This is because a forest in this context is a place where deer were hunted rather than, as we tend to think today, a place dominated by trees. To pick up on the theme of Jo’s post of the other day and also highlight a particular problem within the Forest, I did see a couple of invasive alien species on my short walk. Both were attractive escapes from cultivation and wetland species.

What’s in My Meadow Today?

Although it is perhaps not really a meadow plant I do have a few wild carrot plants in the meadow, like all umbellifers they are very attractive to insects, so I allow them in. The flowers are only just opening and actually look rather interesting just before the flowers open with the head enclosed caged.

30 Days Wild – Day 27: Location, Location, Location

After several days of the forecast promising rain in a couple of days, it finally arrived, although not yet in great quantity it is none the less welcome, so long as it does not get out of hand.

I have been running two moth traps at Blashford on several recent nights and it is remarkable how different the catches are. On trap is on the open ground beside the Centre and the other about 50m away under some trees. One of the most immediate differences that I notice when opening the traps is that the one close to the Centre has hawk-moths in it, that under the trees does not. Clearly the hawk-moths favour flying over open ground, perhaps their fast flight is just not suited to confined spaces, like trying to drag race around the streets of Fordingbridge. Under the trees there are many more smaller moths, is seems probably that they are actively avoiding the open spaces where their weak flight may mean they lose control over where they are going.  It has certainly been a lesson in importance of exact location in determining what is caught.

As a further illustration of the difference that location made is that the trap in the open caught 34 species, whilst the one under the trees 40 species, but there were only 18 species that were caught in both traps. Both have been run for the same time each night, coming on and going off at the same time, the effect would seem to be due to where they have been running. Open sites might be expected to catch less on windy nights but last night was not windy so this is unlikely to have been a factor and both sites are shaded from the morning sun, which might otherwise warm the moths and means some fly out of the trap, so lost moths can probably be discounted too. Clearly I will need to give more consideration to precisely where I put the trap in future as it would seem to be a very important factor determining what gets caught.

30 Days Wild – Day 22: Punctuated

It was thankfully cooler today which allowed us to do some work along the open western shore of Ibsley Water. As it was Thursday the “us” was the famous Blashford volunteer team. We were trimming brambles and pulling ragwort. I know ragwort is a great nectar source, but in this case we are trying to establish grassland where there has been bramble, willow and nettlebeds, this means mowing, but as we have ponies on site we need to remove the ragwort first. Ponies will rarely eat growing ragwort, but if cut and mixed in grass they will and so can get poisoned.

This shore was dominated by huge beds of ragwort and nettles but years of cutting and light grazing are taking effect and we now have mostly grassland with patches of ox-eye daisy, bird’s foot trefoil and other more desirable species. In turn this is attracting insects such as long-winged conehead.

We saw a good few butterflies including good numbers of comma. It seems they are having a very good year and the fresh summer brood emerging now is particularly strong. This generation will breed and produce another generation of adult in the autumn which will them hibernate.

They get their name from the white comma-shaped marking on the under-wing, which is not visible in this shot. Their ragged wing outline makes them less butterfly-shaped and so harder for predators to find, this is especially so when the wings are closed.

I ran two moth traps last night, only about 50m apart, but one under trees and the other in the open. An illustration of what a difference location makes is seen from the number of hawk-moths caught. The one in the open contained 8 elephant hawk-moth, a pine hawk-moth and 2 poplar hawk-moth, whereas the one under the trees contained just one eyed hawk-moth.

As you will have gathered from this blog, I am a fan of insects in general, even horseflies, although I am less keen on them when they come into the office as this one did today.

It is the females that bite, so it would be better if this one went outside again.
