A novel situation

New restrictions imposed by the government (not before time) have the effect of greatly limiting options available for recording wildlife. Yes, a visit to interesting locations, under the guise of 'taking exercise', is still possible but restraint is obviously needed. Accordingly many observations will be from our own small garden.


Fortunately we are currently enjoying unseasonably fine weather and insects are increasingly in evidence. Butterflies are on the wing and today peacocks and commas were noted although only tortoiseshells lingered for long enough to be photographed.


Tortoiseshell butterflies are very attracted to our aubretia.

Our clumps of aubretia are proving a big attraction and I hope to see Dark-edged Bee Flies at the flowers in the next day or two. Spiders, particularly Pardosa species, are dashing around but the Nursery Web Spider, Pisaura mirabilis, seems to adopt a different strategy of waiting motionless on a suitable leaf.

The Nursery Web Spider is easily recognised by its slim build and a distinct
pale stripe on the thorax. Our garden, 24 March, 2020
More tulips have come into flower, with Tulipa humilis, var violacea brightening up the gravel garden. I am hoping they spread and, given a hot dry summer, they should.


More plants of Tulipa humilis are now flowering. 24 March, 2020
I did take a brisk walk today (or as brisk as I could make it). One - to me - interesting thing which caught my eye was the foliage of an Elder, Sambucus nigra, plant in a hedgerow.

An area of mosaic virus was affecting this elder bush.
Badby Road West, Daventry. 24 March, 2020
It had the veining of a typical mosaic virus, and is a fairly well-known affliction of elder. Little can be done other than cutting off and burning the diseased plants. A very similar virus affects honeysuckle and, in view of the fact that elder and honeysuckle are closely related (both being in the Adoxaceae family) this is unsurprising; perhaps the virus is basically the same. Some virus-affected plants are deliberately cultivated, with some tulips being an example.
