Tawny Mining Bee – these are a beautiful species of solitary bees, so useful in spring pollination. The adults emerge in spring and are flying between March and May so this is

the time to look out for the gorgeous amber coloured insects. Since we have made a ‘dry’ bed of pebbles with drought-surviving plants we have had several of these nesting in the garden. The females dig a burrow up to 10 inches deep, with several tunnels off the main hole, hence the easiest sign you have them- small volcanoes of dirt, which tend to become less obvious after a few days. Into each tunnel/cell the female deposits nectar and pollen as food once the single egg she lays in each, hatches. They then hibernate before emerging in spring. We are losing our solitary bee populations so creating a space where they can breed helps a little, and then you get to watch their behaviour (see photo’s). Conditions: Cool, bright weather. Temperature: Max 9 Min 2c.

House Sparrows– The (mixed) results from the RSPB Big Garden Birdwatch are in and ,sadly, small birds have had a bad season, probably due to the exceptionally cold spell in winter. Some would also say sadly, Wood Pigeon numbers are growing in gardens and we are certainly part of that trend. House Sparrows, however, are at last making a bit of a come-back after a big slump in numbers nationwide. We only get them

occasionally in our garden, but many places in Sheffield and the Peak District have good numbers, as you will see from these recent photo’s from a local friend’s garden. I always remember the House Sparrow identification by the male’s grey head being the colour of a slate roof (artistic licence there!) Conditions: Drier and milder. Temperature: Max 12 Min 4C.

We are very lucky to have a pair of Nuthatches regularly coming to our feeders near the window at present, though seldom together. Though they eat insects, foraged with their dagger-like bills from under tree bark (they are our only native species to be able to move up and down a tree) they are omnivorous and come to us for sunflower seeds and fat. Their name apparently comes from their habit of taking seeds with a hard outer case, such as sunflowers, to a tree and wedging it into the bark, hacking (“hatching”) at it to get at the seed inside, a hbehaviour we often watch as they carry seeds off to our nearby trees. Nuthatches nest in tree holes, plastering mud round any holes that are too big until the right snug, safe size. They will also occasionally nest in bird-boxes but they need bigger

Common Green Shield Bugs usually emerge in May, having hibernated over winter in grassy tussocks and undergrowth but these were in the garden a couple of days ago, when the weather was unseasonable mild. This particular Shield Bug (there are several species, named, obviously for their flat, shield-like shape) has, due to climate change,  been spreading North from its habitat in southern England, and feeds on a variety of plants so can be seen in many environments. Also called the Stink Bug, for the noxious fluid it releases from glands if handled or disturbed, the Common Green Shield Bug does no noticeable damage to plants. I’ll be looking out for the eggs they lay on the underside of leaves, and the rounded larvae,

as I have never noticed them before. Conditions: Some gentle rain at last. Temperature: Max 8 Min 1C.
