Pan-species Listing: Top 15 New Species of 2017

2017 has been another fantastic year for me with regards to pan-species listing. I am pleased that I am continuing to add species even throughout the quieter months and although I am sure to slow down sooner or later as the number of species I can add is not infinite, I am still yet to break my steady stride. I have managed to delve into groups I haven’t tackled before such as lacewings and springtails. In this blog post I will list my favourite species added to my Pan-species List in 2017, out of about 700 added this year. If I have written a separate blog post about that particular species, the species name is hyperlinked to that post.

15. Marsh Frog

Adding new non-bird vertebrates is not easy, and so it was great to see several Marsh Frogs on a mid-June day at the nearby Warnham Local Nature Reserve. Although they’re non-native, they come in many different shades of bright green and so are much more attractive than the Common frogs!

14. Purple Toothwort

Plants are more regular pan-species listing additions for me, and although I’m still getting to grips with their huge diversity I have found that attending some Sussex Botanical Recording Society meetings throughout the year has been really helpful. This plant however was found in March, one of my earliest plant additions of the year, at Wakehurst Place. It’s one of several really fascinating plant species in the UK which lack chlorophyll to photosynthesise and therefore gain their nutrients directly from other nearby plants!

13. Waxwing

The winter of 2016/17 was one of the much hoped-for Waxwing ‘invasion’ years, and therefore it would be rude not to see some! The first flock I saw comprised over 30 birds, which is an amazing number for so far south in the UK. It was at a typical setting, an industrial estate! Waxwings often prefer these habitats because of the wealth of berry-producing bushes that grow there. I also saw a couple more later in the year, feeding in a Davidia (Paper Handkerchief) tree at Wakehurst Place, the fruits of which are large and kiwi-like. Very weird food for Waxwings!

12. Vestal

I have been moth-trapping in my garden for a few years, yet save for many Diamond-back Moths I hadn’t caught any migrants in my trap. Autumn presented a window of favourable air-flow from southern Europe and North Africa, which seemed likely to bring decent numbers of migrant moths to our shores. I put my trap out with anticipation on a couple of occasions that week, and on the second I caught exactly what I had been hoping for: 3 Vestals!

11. Stemonitopsis typhina

I have very few slime-moulds on my list like this one, partly because they’re so tricky to identify. However this species, which I came across during a Sussex Fungus Group outing, was a great excuse to research their fascinating life cycle.


10. Wryneck

In September, I was really lucky to be able to venture up to Spurn Bird Observatory in Yorkshire for the annual Migration Festival. Spurn is undoubtedly one of the major sites for rare birds in England and even quite early on in the vagrant season I managed to see brilliant birds such as Long-billed Dowitcher, Barred Warbler, Long-tailed Skua, Short-eared Owl, Caspian Gull, Roseate Tern, Black Tern, Little Stint, Little Gull, and one of my highlights, a Wryneck. This bird showed beautifully well, feeding on the cliff edge near the Sandy Beaches caravan site. It was so great to watch that I visited the bird three times over the weekend to take in the marvellously intricate plumage.

9. Cut-grass

This rather unassuming rare species of wetland grass has a deadly secret! Its blades are exactly that, as sharp as a knife. I didn’t want to test the sharpness on the Sussex Botanical Recording Society outing to Amberley Wildbrooks on which we saw it, however the blades are apparently able to slice through human skin thanks to the minute stiff hairs along the edges!

8. Devil’s Fingers

I’m sure that many people who are lucky to come across a Devil’s Fingers fungus by accident will not be certain that this intriguing organism is natural at all. It bears resemblance to an octopus that had been stuck into the ground upside down, with only its red tentacles emerging from the soil. Furthermore, the tentacles seem to have begun to decompose, with a foul-smelling covering of dark brown goo attracting flies that disperse the fungus’ spores.

7. Green-winged Orchid

Orchids are surprisingly one of the groups that I haven’t seen many of. During the course of the year I added a few species, no rarities unless you count the Greater Tongue-orchids of dubious origin at Wakehurst Place. The Green-winged Orchid was my first orchid species of the year, at Danehill Churchyard. It was great to see the orchids with the nice church in the background, yet I think that the lawn where they were growing was scheduled for mowing. I didn’t have a chance to revisit to check if they were left alone or not, however hopefully they did have the opportunity to flower a little longer.

6. Beewolf

One of the highlights of my summer holiday was a two-day course led by Steven Falk on solitary bee identification at the fantastic Rye Harbour Sussex Wildlife Trust reserve. Of course, although we identified huge numbers of solitary bees, it wasn’t all about them on the weekend. We also came across a large wasp known as the Bee Wolf, which is the invertebrate equivalent of the wild canine. Females will catch adult Honey Bees and bring them back to their nest hole, where they will place the bees in a chamber. It’s within this chamber that the young Beewolf develops. At Rye Harbour, we were lucky to watch Beewolves excavating their nest holes and bringing Honey Bees into the chambers.


5. Queen-of-Spain Fritillary

Birds are the group of organisms most likely to be associated with the word ‘vagrant’. However, during the summer a fortunate lepidopterist found no less than three Queen-of-Spain Fritillaries on his transect near Peacehaven, a species that is unable to breed in the UK as they can’t survive the cold winters. They are therefore very rare summer visitors at best. I am very grateful to the farmer Colin Appleton for allowing lots of keen naturalists onto his land to watch these three regal butterflies ‘lekking’ around a bonfire. Although they apparently travel in groups, explaining why three arrived at once, they are very territorial and the bonfire was the central spot for their territorial disputes, like a boxing ring.

4. Moon Carrot

This wonderfully named plant is not very distinctive, looking very similar to more common umbelliferous plants such as hogweed, yet it’s rare nationally. To make up for its likeness to the other members of its family, it has chosen a spectacular site at which to grow. What seems to be the only modern site for this species in Sussex is the cliffs at Seaford, near the Cuckmere. Some individual plants grow right on the cliff-edge, and look marvellous with the Seven Sisters cliffs in the background. They’ve even made the cover of the new Flora of Sussex!


The Moon Carrot is so-called as it apparently glows in the moonlight!

3. Wood Warbler

I loved listening to a male Wood Warbler sing its heart out at an undisclosed site in Sussex this year, although it was quite a sad experience. This was the first Wood Warbler on territory for 3 years in Sussex, a county where it once used to be a regular breeder. The energy the warbler put into its song was incredible, for weeks it would sing as loud as it could non-stop while hopping tirelessly from tree to tree. Yet due to the species’ rare status in Sussex these days, there was never a female to respond.

2. Lesser Glow-worm

Of all the species included in this top-15 blog post, this one is my most recent find. In fact it was just before Christmas that I found a beetle larva beneath a log at Hedgecourt NR. I sent it to Max Barclay, the beetle curator at NHM London asking what it could be as I was stuck. I had only managed to find one possibility, Phosphaenus hemipterus or the Lesser Glow-worm, however I doubted it was that as it is the rarest of all the glow-worms found in the UK. As far as I know there is only one known modern-day colony in the whole of the country, at a site in Hampshire. To my surprise Max kindly replied saying that he did think it was indeed a Lesser Glow-worm, and he had even received confirmation from another expert on glow-worms! Now we’re just waiting to hear back from some specialists in the Czech Republic before we can be 100% certain, yet it certainly seems highly likely I’ve found quite a rarity!

Despite a thorough search of around 20 logs a few days later, I was unable to find another larva.

1. Wart-biter

At number one, the Wart-biter must be one of my favourite finds from this year. It’s a massive, elusive bush-cricket that’s hard to find at only 5 known modern-day sites in the UK. I visited one of those sites, Mount Caburn on the South Downs, with the Amateur Entomologists’ Society in August specifically to look for this species. The easiest way to find them is to listen for the stridulation (singing), however they only stridulate on warm, calm days and there was a heavy band of rain moving in. I decided to use the highly sophisticated technique of walking around and hoping to chance upon one and it worked! A female jumped from my feet as I was walking, to land in a perfect position for all of the attendees of the field meeting to get an excellent view.


The Wart-biter gets its name from the old Swedish method of getting rid of warts: allowing this cricket to bite them off!

There concludes my top-15 pan-species listing additions of 2017. It was very hard to condense all the brilliant finds into just my 15 favourites, this blog post could easily be 10,000 words long.




Summer migrant at last!

The weather last weekend certainly suggested that spring had sprung and the many signs of the changing seasons about such as flowering Wood-Sorrel and active Bee-Flies supported that fact. However despite the beautiful sunny weather, by yesterday morning I was still yet to see a summer migrant this year!

Early yesterday morning I spent over an hour at the beautifully serene and calm Hedgecourt Lake waiting for a particular species I was hoping to see arrive. Ospreys are apparently seen here every spring and autumn when they travel through on their way to their more northerly breeding grounds. However I have never seen a single one here.

The previous evening (Saturday) not one but two Ospreys were reported nearby at Weir Wood Reservoir just as the sun was setting at 18:30. I was hoping that they would carry on their migration northwards earlier this morning and arrive at Hedgecourt, which is the nearest large waterbody to the reservoir. That is the main reason why I was up nearly at dawn getting ready to wait for one to appear.

Unfortunately I didn’t have any luck with the Ospreys at Hedgecourt although there were some other nice birds about around the lake, with many singing Chiffchaffs, a displaying Sparrowhawk and a male Mandarin which flew in.


Upon arrival back home I heard news that a couple of nice summer migrants had been seen at Weir Wood Reservoir while I had been at Hedgecourt. These were an Osprey, possibly one of the two there yesterday, and a Little Ringed Plover. Encouraged by this news we decided to head to Weir Wood Reservoir to see if we could see either of these birds ourselves.

Weir Wood Reservoir is quite a large reservoir and the whole reservoir cannot be seen from just one viewpoint. Therefore most people visit both ends of the reservoir, the West end and the Dam end. The West end was where we visited first and where the Ospreys were seen yesterday evening and this morning.

Despite the large number of birders at the car park there were few interesting birds to be seen and certainly no Ospreys. According to one of the birders there, Alastair Gray, they can remain well-hidden during a lot of the day simply perched in the trees beside the reservoir and only become noticeable when they set out to fish most commonly in the early morning and late afternoon. They don’t like to fly a lot unnecessarily as it really upsets the local crows which harass the Ospreys until they land! However there was an immature male Goldeneye amongst a group of Great Crested Grebes which was my first of the year.

After searching for hidden Ospreys unsuccessfully we then moved on to the dam end to look for the Little Ringed Plover. The walk up to the dam wall was alive with the song of many Chiffchaffs and the blossoming Blackthorns were full of life. There were a pair of Pied Wagtails on the grassy bank of the dam and a Grey Heron flew overhead.

After walking along the dam wall for a little while to my relief the Little Ringed Plover came into view. It was small and slender, moreso than its relative the Ringed Plover, and was feeding right on the water’s edge. I was able to get quite close, up to a distance of about 10 feet, and from there I was easily able to observe its distinguishing features. To separate Little Ringed from Ringed Plover, the easiest feature to see is the colour of the bill. Little Ringed Plovers have an entirely dark bill whereas Ringed Plovers have a bill with an orange base and a dark tip. Also,  if you are close enough, you might be able to see the yellow eye ring of a Little Ringed Plover which is a feature absent in Ringed Plovers.


The Little Ringed Plover

Although Little Ringed Plovers are regular breeders in England and Wales in the modern day, they first bred as recently as 1938. Their expansion across southern Britain is partly due to the creation of man-made habitats perfect for breeding such as water-filled gravel pits. Now over a thousand pairs of these small waders arrive here each spring to leave again in late June/July.


I am pleased that I have now managed to find my first ‘proper’ summer migrant of 2017. Over the coming weeks, migration is set to pick up as winds become favourable and it becomes warmer. Hopefully I will soon be waking up to the song of Blackcaps and Willow Warblers!
