30 Days Wild – Day 3

I had high hopes for the moth trap this morning and I have to say I was a little disappointed, so rather than a moth, my insect from the trap for today is a true bug, a striped plant bug, proving once again that it is not only moths that are attracted to moth traps.

Outside the Centre at Blashford we have a number of planters filled with plants chosen to attract insects. It is not just the plants that can attract then though, we also have a number of wooden posts with holes drilled in them which are used by nesting bees and especially mason bees. At this time of year the species using the largest holes is the red mason bee. These bees, about the size of a honey-bee make cells for each larva which they provision with pollen and then seal up with mud.

Around the Centre the gravel has been colonised by lots of plants that do well in well drained conditions, such as marjoram, dark mullein and hedgerow cranesbill.

Where it is less trampled and perhaps not quite so dry the vegetation is taller and at this time of year the bright flowers of green alkanet are very obvious and popular with several of the smaller bee species.

Both this plant and the cranesbill are believed to be old introductions to this country from the near continent. A fair bit of out flora has been imported, by accident or design, much that has come from just across the Channel has settled in and now lives like a native. These species have often come with their own insect and other controls and so don’t get out of hand, unlike some introductions from further afield which have often left their escaped their natural controls, which is why they can do so well and out compete native species.

Out in the Garden

Like most people who are lucky enough to have one, I have been spending a lot of time in the garden recently. Our garden is almost exactly the average size of a UK garden, so a little larger than most people will have, but still not a large plot. It does allow space for all the elements with a flower border, vegetable plot, lawn and most importantly a pond and mini-meadow. The aim has always been to maximise the opportunities for wildlife within a more or less conventional garden space and I am really pleased that it was as there has enough wildlife to keep me interested throughout lockdown.

Although the garden is very short of trees and shrubs the variety and features such as the meadow seem very attractive to lots of birds, probably just because it offers home to a large number and wide variety of invertebrates, the main food of nestlings.

As we have been sitting out a lot it is really noticeable how much more tame most of the birds have become, a feature not just of birds that use the feeder, they just seem to have got used to us being out there.

I took the chance to refurbish our pond, which had evidently sprung a leak, so it was relined and filled from the water butts. In no time it attracted eight smooth newt and several damselflies and even egg-laying broad-bodied chaser with an attendant male.

The mini-meadow, which with the area of the pond is in a 5m x 4m space is the main attraction for most wildlife. It was made by initially allowing the existing grass to grow and cutting and removing the vegetation once a year. I then added some seed and a few small plants that I grew from seed and over the last five years it has developed.

A flowery meadow is, unsurprisingly very popular with butterflies, over the last few days I have seen my first small copper and common blue of the year in my garden, both species I think breed in the meadow.

Lots of other insects live in the meadow, most obviously lots of ants, I now have a number of anthills dotted about the patch, you may have spotted a couple of ants in the common vetch picture above, probably collecting nectar from the base of the flowers. A range of true bugs are wandering about, mostly, but not all, vegetarians.

There has been a lot in the media in recent times about bees and pollinators. You could be forgiven for thinking that pollination is dependent upon honey-bees, occasionally in very industrial scale agriculture this is almost true, but generally this is far from the case. In fact it turns out that more diverse environments have more pollinators and more different types of pollinators, we have a pollinator “problem” because we have impoverished our environment. I notice in my garden that having lots of different plants with differing flower types results in seeing lots of different types of insects and especially different species of bees.

The ashy mining bee is one very distinctive species of spring-flying solitary mining bee which is increasingly visiting gardens. Pollination is carried out by almost all insects that visit flowers and even by other creatures like birds and small mammals. Recently the importance of moths has received some attention, as they fly at night their role is often forgotten. Hoverflies are more obvious and it is easy to see them visiting lots of flowers, often with a coating of pollen grains. I was interested to see a species I did not recognise recently int he garden and luckily got a picture that was good enough to identify the species. It turned out to be a recent colonist to this country with larvae that eat house-leeks, it may have got here under its own steam, but more likely was brought here as a result of the plant trade. It was first found in 2006 and now quite widespread across the southern part of the country.

Bee is for Blashford

Or maybe Blashford is for bees, well of course it is! Blashford is for all wildlife and the people who like to experience it. Everyone knows the honey bee and bumble bees, although perhaps not that there are 28 species of them. However there are something like 250 other species of bees in Britain and they all spend their days visiting flowers and pollinating them. These 250 are the so called solitary bees, despite the name they can occur in great aggregations, importantly though each nest is the domain of just one female, there are no worker bees.

There has been much coverage recently about the declines in insect numbers around the world and that of pollinating insects in particular, perhaps because they are economically important to us as pollinators of crops. Declines could be for many reasons and probably are multi-factored, but a general loss of habitat and an increasing uniformity in what is left, along with increased prevalence of chemical contaminants are all likely contributors. Some enlightened local authorities are modifying their grass mowing regimes on verges, roundabouts and recreation site to allow more flowering, some of the best are actually seeding back wildflowers or using “meadow mixes”. In fact we can all help by providing flowers that are good sources of nectar and by valuing some of the “weeds” that we might have removed in the past. For instance a lawn with dandelions may not win the green-keepers prize but these are a very important source of food for early flying bees and hoverflies.

Blashford Lakes has lots of nectar sources, especially at this time of year when willows are important for many species and so has lots of solitary bees. Many also need bare, sandy soil to dig their nests and we have that in abundance too.

One of the problems with solitary bees is that some species are very similar to one another and so difficult to identify in the field. Although the grey-backed mining bee female is distinctive the male looks very like the male of another species, the ashy mining bee.

One of the commonest mining bees around at present is the yellow-legged mining bee, which can be found nesting in bare ground in banks, lawns and various other places.

Some bees are neither colonial nor make their own solitary nests, they are nest parasites of other bees. One genus of bees the Nomada bees specialise in this way of life, often specialising on one particular host species. The yellow-legged mining bee plays unwilling host to the painted nomad bee, which looks very wasp-like.

The last few of days have seen big arrivals of hirundines, Monday was almost all sand martin, yesterday there were a few swallow and the odd house martin and today there were even more swallow, probably over 50. On Ibsley Water there a couple of pairs of oystercatcher, a pair of redshank, probably five little ringed plover, several lapwing and today two green sandpiper. Meanwhile around the Centre and Woodland Hide the wheezing of brambling is very much in evidence, particularly in the morning, there are at least 30 and I suspect 50 or more around just now.

And remember it does not take much effort not to mow the lawn for a few days and let the dandelions flower to feed the bees. You could put your feet up and have a cup of tea, or a beer (other drinks are available), whilst making your own contribution to Wilding Hampshire!
