My top ten natural history highlights of 2019

Posted by Graeme Lyons , Friday, 3 January 2020 08:55

Never before have I agonised over the order of my top ten natural history highlights but I do not exaggerate when I say 2019 was the best natural history year of my life. Anyway, spiders are here lumped as one and will get their own top ten at a later date. So here they are in reverse order.

10. Carabus intricatus (Blue Ground Beetle) with John Walters in Devon. 
It was hard keeping John in eye sight on the side of the hill so I was glad that he was able to find us one of these astonishingly smart beetles. December was an exceptional month for me in nature.

9. Purple Emperor (Apatura iris) larva beaten from willow at Holmwood Common.
Not a really rare species but my first encounter with the larva in September produced some unforgettable photos.

8. Snow Fleas (Boreus hyemalis). 
Both on purpose in the Wyre Forest, Shropshire in February and by accident on the Roaches in December.

7.  Mega rare moths found in the field, who needs a moth trap?
I found a LOT of rare moths, probably the rarest was this Purple Marbled that I managed to capture even without a net at Seaford Head during a bioblitz. Others this year including sweeping a Dewick's Plusia in a park in London and netting a Hornet Moth in flight on a freelance job in Kent. 

6. East Head sand dunes invertebrate survey. 
A summer surveying these sand dunes with Lee Walther for the National Trust was a blast. Still I think the site with highest proportion of species with conservation status I have ever surveyed. Here I have picked the sea-lavender feeding weevil Pseudaplemonus limonii as it's metallic purple!

5. Sea slugs at the Pound
My annual trip to the Pound at Eastbourne with Evan Jones was mid blowing last year and it's testament to how amazing a year this has been that this is way down at number five. Here is the one that blew me away the most and pretty much the only one I found myself, Polycera quadrilineata.

4. The baseline survey of Ken Hill Estate
My trips up to Norfolk this year were so enjoyable, so many great things to find but the day I recorded Breckland Leatherbug Arenocoris waltlii might be the most memorable.

3. A year of spiders
OK, here's the big shock. I have loved year listing spiders (and I will be giving them their own top ten very soon) but it doesn't make it to 1st or even 2nd place. Who will win the spider top ten? I suspect it might have to go to Philodromus fallax for being the most unexpected find in early November that I had almost given up on and one of my most sought after species of all time.

2. Melodious Warbler and breeding Dartford Warblers at Butcherlands
The Butcherlands bird survey has delighted me for nearly a decade. So the breeding Dartford Warblers in bramble scrub were amazing but then picking up an odd warbler in the distance on the last visit, chasing it, realising it was a bird I didn't know was possibly the most exciting thing ever. Especially as at one point it was getting away from me. Then a great big yellow warbler jumped right out in front of me, a Melodious Warbler!. Definitely the fastest song of any bird and a great way to end a very enjoyable survey. When I first picked it up it was in the big willow on the left.

1. My first first for Britain!
Not only a new species but a new family for the UK. Finding this at Marline Valley was such an exciting experience. What a strange looking thing. It was closely followed by a second specimen swept by young Ted on his work experience! I tentatively identified it as Coptosoma scutellatum and Tristan Bantock soon confirmed the ID and I gave it the English name Trapezium Shieldbug. A really exciting way to end 12 years at Sussex Wildlife Trust but I have to end this on a downer. It probably turned up in the hot summer of 2018 and this in turn is almost certainly down to man made climate change. 

We now have a government woefully inadequate in terms of its approach to climate change and emissions, so you have to do every little bit you can to prevent things from getting any worse. I don't think people realise just how important five years is in the crisis we are in now, I know I am preaching to the converted here but we just missed a huge chance to make serious change to our environment at this crucial tipping point in the climate crisis and influence others on the world stage.


But I know what you're thinking. "Where ARE its wings?!". Now lets see what 2020 has to offer...

Peak spider

Posted by Graeme Lyons , Monday, 23 December 2019 08:57

The Roaches will always be one of the places that absolutely blow me away. Only 35 miles from where I grew up (as far as Iping Common is from home) but it felt like another country growing up. So this morning I headed to this site to do some upland spidering and had a pretty awesome day. I got a lifer in the first sample. The embarrassingly common Poecilonta variegata. It's great coming up 'north'!

Then on the second suction sample I got another lifer. It wasn't until I got home that |I realised which Bolyphantes I had but all the specimens I took were Bolyphantes luteolus and not the more northern species. And at about 400 m I saw on my phone that Matt had pulled ahead meaning we were now level-pegging on 373. The tension!

I suction-sampled a lovely adult male Walckneaeria acuminata. Look at that eye turret!

It got a little colder and I slowed down but the surprise of a male Snow Flea in the suction sampler was awesome!

It's such an alien landscape. Love it up there. My first Red Grouse in over 15 years was a welcome distraction.

Plants I grew up with like Crowberry and Cowberry seem exotic to me now.

At over 450 m, Megabunus diadema was surprisingly hardy. A new 10 km square for this species.

Then I found what I was looking for, some stones to turn over. Here is an adult female Segestria senoculata at nearly 450 m.

A Hedgehog Slug.

I picked up two female Centromerus prudens, another lifer for me (374). What also turned out to be a lifer, the nationally scarce Porrhomma montanum  below (375). And I have just spent an hour figuring out what the last spider was, another nationally scarce lifer!!! Scotinotylus evansi (376). Now, I'm off back up north to Gun Moor...

Snow Flea Circus

Posted by Graeme Lyons , Saturday, 2 February 2019 19:59

Have you ever taken a 400 mile trip for a flea? Well me neither. Snow Flea Boreus hyemalis is actually a mecopteran, basically a small, wingless, winter-adult scorpionfly. Less than a week ago I got a message from Tony Davis saying simply "How's your back?" I knew this meant he had another crazy mission for us and I had the weekend free, definitely a great opportunity for some escapism...all the way to the Wyre Forest. We were just into Shropshire, just a few kilometres from my home county of Staffordshire but a part of the world I know very little about. The names of the towns and villages there completely alien to me. The last time I went to the Wyre Forest I was at school, |Steve Copper took us there to look for Drab Looper moths.

It took 25 minutes to find the first Snow Flea, the female above. We then went on to find a further six in a total of two hours of searching (two females and five males in all). Tony had the gen pretty much perfect. Here is how the first female appeared to the naked eye at first.
And the habitat. A south-facing bank with dense Sessile Oaks. Plentiful mosses at the bases of the trees are where we searched and this payed off. I thought there was some association with the moss Dicranum majus (which you can see in the image above to the left).

Here is the habitat...

And some video of the female.

And here is the male, with the strange vestigal wings and unusually-shaped first abdominal segments. I think their 'beak' looks quite like that of a Cormorant.

And some footage of him. I had no idea that they can jump quite substantial distances. I didn't manage to capture it (they behaved very well for me, not so much for Tony) but pretty obvious where the English name comes from after seeing this. A big thanks to Tony for arranging this and driving most of the way, never thought I would see these bizarre and fascinating insects. Now, I wonder if I can find them in Sussex...
