Another that I've been expecting.


Oak Processionary. A moth to strike terror into the heart of the general public...

In Southern Europe, where the species naturally occurs, the ecosystem is balanced so that the moths have natural predators to keep the numbers under control, but further north - where due to slow expansion and accidental introduction - there is not. This species can take over areas and cause human suffering via irritant hairs that are found on the caterpillars, (which can break off and become airborne, finding their target with ease).

Since 2006 an increasing number of records have come from south-west London, and, even with council controls such as spraying infected trees, the expansion creeps on. Until today I had not recorded the moth at the garden MV, but this morning one finally turned up. Along with Box Moth, a garden addition that is not really good news.


Back in 1987, when I first switched the Banstead garden moth trap on, I would have laughed out loud with incredulity if someone had told me that by 2018 the following would be resident: Tree-lichen Beauty, Jersey Tiger, Toadflax Brocade, Small Ranunculus, White-point and Cypress Carpet. And they're just the species that come right off the top of my head...

Goldfinches and Lavender

Image
We have three medium-sized Lavender bushes in our back garden. Throughout the summer the flowers (which last for several months) are a magnet for insects and give off a most restful aroma. As tempting as it is to cut the dead stems in the autumn, we always leave them, as we know that during the late winter we will get visitors to feed on the seed heads... This video was taken from the kitchen window this morning. We will normally see one or two birds over a few days, but have had up to 14 at once. We never tire of watching them. Lavender is a wonderful plant to have in the garden, with year round natural history benefits. So what are you waiting for? They are readily available at a garden centre close to you right now! There is an historic association with Lavender in this part of northern Surrey and south London. Lavender fields have been harvested for many years, with one particular field close to Woodmansterne being very popular with day trippers. A significant proportion o

To tell it like it is, or not...

I am grateful to Gavin Haig (Not Quite Scilly) who drew my attention to an opinion piece, penned by Matt Phelps, which appeared in the November issue of 'Birdwatch' magazine, entitled 'Positive Approach', which I have now read. In it, he suggests that there is too much negativity being posted on social media regarding the state of our birding world, which is then acting as a deterrent towards a younger generation in adopting conservation and wildlife study. He also suggests that a lot of this negativity is being generated by older birders, and that these old timers keep banging on about the 'good old days' which isn't helpful in encouraging the youth to pick up a pair of binoculars and get out into the field. Does he have a point? Now, I am undeniably an older birder, and I am also guilty of having posted, blogged, written and spoken about the slump in bird and invertebrate numbers. I also like nothing better than to revisit my notebooks and share in the hi

Time to reflect

I normally come up with the title for a post after I have written it. If I'm feeling creative it will be some sort of play on words, or if I'm not then an all-encompassing word or two will do. As for this particular post, and with a few things to discuss, I've written the title first, inspired by having just read a feature about musicians who have used the title of an album as the starting point for their creative exercise. Here goes... Firstly, blogs - yes, this very medium that I am writing in and you are reading from. - what content they derive, the reason that the content exists and what the writer should (or should not) expect from any reader that visits the blog. This was brought into sharp focus by a series of posts to be found here, at Jono Lethbridge's excellent 'Wansted Birder'.   His blogging output has recently included detailed and entertaining reports on his recent overseas trips which have received a bit of flak from certain quarters. None of us b
