It’s been an interesting couple of weeks for migrants (of the insect type) in our garden and around Malvern, so I thought I’d collate what we’ve been seeing.
First up an insect that is really only a migrant by name – the Migrant Hawker (Aeshna mixta). A beautiful dragonfly that used to be fairly uncommon in the UK – hence the name Migrant, but is now well established. This particular one was buzzing for insect prey on some rough ground at Chris’ workplace.
We’ve been blessed with at least one Painted Lady butterfly (Vanessa cardui) in the garden most days for the last month or so, but apparently we are not alone. Every few years the country gets a “Painted Lady Summer” when they come over in huge numbers from abroad – and this is one of those summers. Some people have reported seeing them in their hundreds (a friend of mine in Edinburgh got driven inside by having so many of them on her patio it freaked her out!). Sadly we’ve not had that many, probably because we’re the wrong side of the country, so the most we managed to count on the buddleia was 5 at one time. But that’s a record for us, so we’re happy to see them even in low numbers.
We tend to be more lucky with the moths. First a very small migrant moth, but one which some years can come over in huge numbers. The Diamond-back Moth (Plutella xylostella) is only a few mm long, but somehow manages to survive the journey over from the continent and into our Malvern garden. Most years we only get 1 or 2 at a time; the most we’ve ever had in the moth trap in one night is 20, but they can apparently arrive in their thousands. Not the greatest photo of this one below, but you can at least make out the joined up diamond pattern on its back.
A larger macro moth – the Silver Y (Autographa gamma) is another one we see regularly in low numbers. They have a characteristic Y shaped mark on the wings (although admittedly it is upside down) and are often active during the day. The first one I ever saw, was nectaring on some lavender during the day – I thought initially it was a Hummingbird Hawkmoth from the way it moved, but know better now!
We have seen genuine Hummingbird Hawkmoths this summer, but I’ve not managed to get any photos – they’re just too fast and I’m just too slow most of the time. But here’s one we did manage to catch a couple of years ago.
Undoubtedly though the highlight of my moth-ing career so far, and probably the best catch I’ll ever get, was one from a fortnight ago. I’d been enviously enjoying photos of Bedstraw Hawk-moths (Hyles gallii) on various social media for a couple of weeks, but never dreamt I’d be lucky enough to catch one in our garden. But at the beginning of August I got up to empty the trap and nearly fainted at the sight of a Bedstraw Hawk-moth sitting there. I was so nervous opening the trap in case it flew off – no-one would ever believe me unless I could get a photo of it! Fortunately it was a docile beauty that didn’t object too much to being potted up and photographed.
I posted some photos on Facebook and a few fellow moth enthusiasts came round to see it before I released it unharmed. When I put it out on some Rose Bay Willow-Herb, it vibrated its wings for a few seconds to warm up:
Then it shot off like a rocket. We have a large buddleia bush nearby and it circled that a few times. I watched in horror as 3 sparrows flew out from the bush trying to catch it, but thankfully the moth was quicker than the birds and it got away. Don’t think I could have lived with myself if I’d seen it get eaten by the sparrows!
I am told this was only the 5th record of a Bedstraw for Worcestershire and probably the first record for Malvern. I doubt I’ll ever see another one and unless a Death’s Head Hawkmoth lands in the garden, I doubt I’ll ever have a more exciting moth find. But each weekend from now on I will open the moth trap in hope because you just never know what is going to be in there!
