Early bird


I was going to say that my second night with the moth trap this year saw the guest-list increase by 100 percent, but some warning bell sounded from 1966 when I scraped through maths O level with grade 6, the lowest which still constituted a pass. A hundred percent of nil is nil, it reminded me. So the fact that I got one moth last night was an increase of a different order.

The moth is a Pale Brindled Beauty, a traditionally early flyer with a reassuring amount of fur coat to help to keep it warm. It wasn't actually in the eggboxes but perched on a section of the bulbholder which was gently warmed by the nearby light. In the hope of photographing its underwings, I gave it a little tickle with a twig and it obligingly fluttered down to the grass and revealed all. That includes - picture below - the slightly pinkish tone of its body colouring, the sign of a freshly-hatched specimen.



Here it is again, below, on a scrap of eggbox, showing the fine antennae which almost always mark a moth out as male, because of their role in detecting the pheremones given off by females. Actually, you don't need to see these to know the gender of the moth. Take a look at my final picture of the Pale Brindled Beauty's poor old flightless female, who is in fact an example of evolutionary success. She sits contentedly on a tree trunk, safe from the dramas of night flight, and waits for a male to arrive and do the business, before laying her eggs and starting the cycle off again.




I have been catching up at last with my records going back to our move here from Leeds in the Spring of 2013. So I can tell you that previous debuts by the PBB have been: 3 Feb in 2014, 1 March in 2016, 17 Feb in 2017 and 2 Jan last year. I only trapped for a couple of nights before April in 2015 and had no bulb until April in 2018.  It has been the first moth to arrive every year except 2016 and now 2020 when it has had to be content with the silver medal.

Good to see you up + running Martin. I attended our first monthly catch last weekend + we managed 7 species. When I got home found white-shouldered House Moth, so 8 species for the day. Hope it's going to be a productive year!
