I've caught the Jersey bug

Posted by Graeme Lyons , Wednesday 31 May 2017 06:50

The sun came out on Jersey today and so did the bugs! What an epic day we had and I really had a chance to get my new camera to work. We spent most of the day in the huge Le Blanches Banques Dunes to the south west of the island. The island seems to be really good for bugs, first up with have an island speciality being Broad-shouldered Shieldbug. We only saw one of these all day.

I reckon this is the nymph of Dicronocephalus agilis but it's what this nymph led me too that was a real surprise.

As I was trying to keep pace with this bug. it crawled right by a tiny plant. A plant I searched for many times on the cliffs at Beachy Head. The incredibly rare Small Hare's-ear!

Back to the bugs and another island speciality, White-shouldered Shieldbug. Again we saw only one of these.


And this is incredibly rare in the UK being known from one site in Cornwall. It;s the Cornish Shieldbug.

Another species not recorded from Sussex is the Sand-runner Shieldbug. And odd little thing, we only saw one of them.

Here is a mirid, common on the island but rare in the UK. Capsodes sulcatus.

And I've seen this one a few times, it's only at Rye Harbour in Sussex but it's always nice to see. Lesser Streaked Shieldbug.

Plants were good such as this Small Melilot. It's not always easy to tell what's native or not on the island but I expect not with this one being along a road.

And the invasive succulent Purple Dewplant which is a real problem on the coasts.

And I think these two are Sticky Storksbill and Musk Storksbill respectively. Come to think of it I didn't see much Common.

Back to the inverts. I had three new bees so far but this was the only one I photographed. Silvery Leaf-cutter Megachile leachella.

We caught several flies, one very exciting one that I managed to let go.However, I was pleased to find a couple of these beauties. The Dark-cloaked Bee-fly.

We reckon this must be the nymph of Blue-winged Grasshopper!

A little further north and I we heard lots of Field Crickets. I was also able to redeem myself somewhat with Chris and show him a huge male.

And finally the beetles. I believe this is Chrysolina haemoptera.

But this was my favourite species and my favourite photo. Because I had never heard of it before yesterday. I am tentatively at this stage calling this the Rugged Bloody-nose Beetle Timarcha rugulosa. I should add I made that English name up but I like it as it fits and makes it sound like a total bad ass. This is the photo-stacking feature working at its best.

Oh yeah, we had European Green Lizard too but it was too fast for a photo! Wow, so much to see here. Loads yet to identify from too, I've taken so many photos. The bets thing about all this is that we decided to allow the Channel Islands in PSL. So coming here just adds to the feeling that you are in the Med whilst being in the UK at the same time. I LOVE Jersey and its natural history. So today we are going to some commons followed by rock-pooling at a VERY low tide. Watch this space!

It's 6.30 am and I've just slept for 10 hours after an exhausting and damp start to my first trip to Jersey! I'm here with Chris Bentley and due to getting the dates wrong, I was completely unprepared for my trip being somewhere in Hampshire when he arrived to pick me up! It's all worked out in the end though. We got here yesterday about 2.00 pm and met Simon Robson on the west coast of the island where he took us to look for a bug he found new to the British Isles last year year (Simon says it makes me and Chris the third and fourth people to see it!).  It was very wet though so we struggled to find many inverts although we could feel the potential everywhere. Here is Micrelytra fossarum on Purple Viper's Bugloss, both new ones for me. The plants here are gonna be amazing.

And what I think is Small-flowered Catchfly.

Then we hit the orchid meadow and I was pleased to see that the Lax-flowered Orchid was still well in flower and what a looker that is!

Whilst I was photographing the orchid, Chris said "What's that yellow stuff?". I was completely surrounded by yet another plant I've not see, Yellow Bartsia.

And only my second Cassida nebulosa. So, it's nearly time to eat my own weight in complimentary breakfast before we go and spend the whole DRY day in the most amazing dune system I have ever seen. A big thanks to Simon for meeting us at such short notice. Get ready for part 2!

Even more incredibly rare spiders found on an old conifer plantation!

Posted by Graeme Lyons , Tuesday 23 May 2017 18:59

Where do you start with a day like today? The invertebrates came thick and fast, as they so often do at Graffham Common. When we acquired the site in 2009/10, it was mostly conifer plantation with some nice heathy clearings and an old bog, that were quite rich with invertebrates. We were very keen to maintain and enhance this interest when took the trees off, so we left around 70% so that the site felt more structured. It continues to throw up surprises. The Philodromus margaritatus from last time has been confirmed. This time the star of the show was completely unexpected yet again being the bizarre looking Uloborus walckenaerius. This strange spider is known in Sussex from Ambersham Common and one other site up on the border with Surrey. Beyond that it's well established on the Surrey heaths with some older records in the New Forest. Now it's not that far from Ambersham Common to Graffham but we have looked at this site in detail (I have swept the Hell of the established glades and not seen a single Uloborus there). Today we found FIVE adults on the western side of Graffham, all in the building phase of Heather and none in the old established areas. This is hugely significant as the spider was only found today in areas of Heather that only five years ago were under pine and bracken. It's a great conservation Sussex story and shows the benefit of joining up sites! So it's a new species for the reserve network and a welcome RDB3 species to this surprising jewel of a site.

It was a fascinating spider to watch, pulling itself along upside down along lines of thread sent out from one patch of heather to the next. The underside of the abdomen is dark which seems like a way of breaking up the outline when it's at rest. They also don't keep still so I struggled to get that perfect shot. 

But the fun didn't stop there! On the east side I swept this HUGE Xysticus and it's Xysticus luctuosus. Now we found it at Graffham west in 2009 in pitfalls (it's still the only Sussex site for this species but we are the first to see it alive!) but I wasn't doing spiders then (Andy Phillips did the identifications) and it's took me this long to find a live one. This is a big Xysticus (9 mm this female). She was still enough to use the photo stacking function on the new camera and I was really pleased with it. This was a new species for me.

Right at the end we recorded Sibianor aurocinctus AGAIN. In fact I think we recorded eight species of jumping spider today which is a record for me.

Now for the beetles. This species is new to all our reserves, it''s the naturalised weevil Magdalis memnonius and feeds on pine wood.

And a trio of longhorns provided cameos throughout the day. Such as Pachytodes cerambyciformis.

Stenurella melanura
And Rhagium bifasciatum

This carabid has been recorded there before, it's the stunning Agonum sexpunctatum.

Jane accidentally swept this Golden-ringed Dragonfly, a stunning creature.

We also saw the first Dodder growing on the site, Woodlark with three fledglings, Cuckoo, Tree Pipit, Firecrest, Hobby and Spotted Flycatcher!

Oh and in one small patch of Bilberry, clouds of this little tortix moth that I think is the Bilberry Bell Rhopobota myrtillana. IF it is this species, it will be a first for Sussex, having a very northwestern distribution. Watch this space for this one!

Not bad for an old conifer plantation hey? Well done Jane!

A new shieldbug for Sussex!

Posted by Graeme Lyons , Saturday 20 May 2017 16:50

So this isn't my find, it's Derek Binns who got this smart looking beast. I was notified via Twitter of this and Tristan Bantock confirmed the ID, I've never heard of it! So, the following photos and words are all Derek's but as county record for Heteroptera, I thought I should promote this amazing find. What a smart looking beast, if you see one out there, please send in your records!

"Searching for invertebrates in the margins of the old quarry in Hastings Country Park has produced unexpected rewards. Whilst checking a reasonably large patch of spear thistle, two purple shieldbugs were found. One was the Hairy Shieldbug Dolycoris baccarum, an attractive native species that can be found in good numbers on woodland margins everywhere. The second shieldbug warranted more than a second glance. It was a species that is reasonably common in France but does not occur in this country. There are no more than one or two records of it getting across the Channel to our shores, and this was the first record for Sussex.

Many photographs were taken so as to get sufficient detail to allow accurate identification as there is taxonomic debate about certain species in this difficult genus. A note was sent to the national recorder for heteroptera to ask for confirmation that this was Carpocoris purpureipennis, and after some discussion and reference to specific details on the pronotum and scutellum, the identification was confirmed, The county recorder was included in the discussion, and he confirmed it to be a first record for Sussex. If you start with a mental picture of the native Hairy Shieldbug Dolycoris baccarum, this species seems at least half as big again and the pronotum shoulders project noticeably, also the scutellum is very obviously different from the Hairy as colouration of the top of the scutellum blends into the pronotum which has longitudinal stripes that continue onto the head. The wingtips extend to a buff point beyond the body. The striped connexivum around the sides of the rear half of this bug are a very bold cream and black stripe and is a lot more convex than the black and white striped connexivum of the native Hairy Shieldbug. In the field this area appears to be a striped circle that is broken by a “tail” formed from the wingtips.

As many species of shieldbug are at the northernmost edge of their range in this country, the prospect of global warming gives potential for some european species to cross the Channel. A site such as the quarry which provides sheltered warmth close to landfall after migration might be considered to have potential for a colony to establish. Further observations will be made as the summer progresses to see if this shieldbug is a lone record or not."

Last week, Alice and I did a 'mini-bioblitz' at Gillham Wood. One of our smaller sites with no designations (in over seven years of blogging, this is my first post about the site!), it's much lower down the priority list for monitoring. This means we don't do much structured monitoring there, it's simply not going to greatly inform management. It's at sites like this that casual recording is welcome though, so we attempted to see if we could beat the 108 species noted on the spreadsheet. We did, with 145 species in just over two hours. The highlight was this micro moth which I beat from a Hawthorn on the southern edge of the wood. It's Spuleria flavicaput (what an awesome scientific name?) or the Yellow-headed Cosmet. The are only six records in the county so it's quite a goody abd it's new to the whole reserve network.  It's my 1045th moth and 6545th species. It's the 1233rd moth on our reserves and the 9846th species we've recorded on our reserves so far. We also recorded a few nice ancient woodland indicators such as Pignut, Wood Speedwell and Butcher's Broom.

Now for the bad news. My back has gone again and this time it's pretty bad. I had thought that last week's flare up had resolved itself as yesterday I mostly felt fine but this morning the disc has got much worse and my left lats have gone into spasm. It's pretty bad when both happen at once. I have only three weeks left before the 1000 species challenge! Dave has suggested he'll be carrying me around on a stretcher. Maybe we could get some Segways?

This post has been brought to you by the medium of opiate based pain killers and Libby's birthday cake which has more sugar in a slice than I've eaten all year. Now to catch up with entering some records, my 40,000th record is coming up!

A couple of weekends ago, Dave and I had another go at limbering up for the 1000 species challenge (that's the two of us aiming to see and identify 1000 species or more in a 24 hour period on the 10th June). We did 400 species in 4 hours and 16 minutes which I am pretty pleased with. Most of this was from two sites with a bit of Burton Pond tagged on at the end. The highlight for me was this mystery caterpillar that I had to admit defeat on. I ended up going right up to the top of Butterfly Conservation to get a species name. It's none other than a Pale Eggar. This was my bogey moth for a long time. This was beaten from oak in Dennis's Croft in Ebernoe. It's quite a scarce moth that I have only seen once or twice before.

Anyway, four hours was hard work but I reckon we are going to make it on the day, weather permitting! We will have our hands full but are hoping somehow to do social media and photographic updates on the day but this might need the help of some other friends. We have our (top secret) route planned and we think it's a good one but time will tell. So don't forget the 10th June 2017, we certainly won't!

Fund raising for the 1000 species challenge has now started, so please sponsor us what you can here at our Just Giving page.
