How A Nomad Helped My Confidence

This week saw my first office day at the Wildlife Trust BCN as a Volunteer Communications Officer. Alongside writing a piece for their blog, assisting with a competition and learning more about how the communications team functions, there was a particular aspect to the day that has since become very memorable. The lunch break.

Now I didn’t have a very exciting selection of food for my lunch, but it was eaten outside in the beautifully warm spring sunshine. Brimstone butterflies (Gonepteryx rhamni) flitted through the garden, bees worked hard to collect pollen and a Chiffchaff (Phylloscopus collybita) called from a nearby tree. Being the keen naturalist that I am, I was mentally noting down the different species about – Goldfinch (Carduelis carduelis), Blue Tit (Cyanistes caeruleus), Red-tailed and Early Bumblebees (Bombus lapidarius and B.pratorum), Rosemary Beetle (Chrysolina americana), 7-spot Ladybird (Coccinella 7-punctata) and so on, all of which would be put into my wildlife records notebook. Further to being a naturalist, I am a pan-species lister which means that I am extra excited if I see something new to me. And during this lunch break, I did just that.

I was watching and photographing some bees on the rosemary (NB: I need some for my garden, it is brilliant for pollinators!) when I noticed another insect nearby. With its wicked looking markings, I thought that it was probably an ichneumon wasp species (Ichneumonidae). I snapped a few photos, taking care to get it from different angles, before it wandered off into the undergrowth. I decided against potting it, I didn’t think I would be able to identify myself and figured it would be better off in the wild.

So that was my lunch break, all in all, the type of lunch break I love. Warmth, sunshine and wildlife. I didn’t think much more of it until later. I got home and downloaded the camera photos onto my laptop, whilst flicking through my insect book to find Red Mason Bee (Osmia rufa), a species that I had seen for the first time recently and needed to put a tick next to in the book. I was in the Hymenoptera section (bees, wasps, ants) and as I flicked through, I saw something vaguely familiar – a group that looked like that insect from earlier. But it wasn’t the ichneumon wasp section, it was the Nomada bees group.

After a bit of thinking, and a sip of tea, I decided I would give the identification a go. If nothing else, it would show me whether this group is ever ‘doable’ from photos alone. Immediately I felt a little overwhelmed … the Nomada bees do look pretty similar to each other! Rather than trying to focus on each species at a time, I drew up a shortlist of potential species, casting aside species that I decided against – too much yellow on the abdomen, stripes on the thorax and other such characteristics.

I ended up with a shortlist of 6 potential species, and I turned to a more detailed, and wonderful, book (Falk – Field Guide to Bees of Great Britain and Ireland) to examine each of these species in turn. I slowly read through each description, flicking back to the anatomy page when confronted with technical terms (tergites, labrum, pronatal tubercules), crossing the species off if the description didn’t match the photograph in front of me.

In the end, I was left with one, Nomada ferruginata also known as the Yellow-shouldered Nomad Bee. The technical bits in the description matched up:  the pronatal tubercules were yellow (i.e. small yellow circular lump on the thorax), there were yellow spots on the tergites 2 and 5 (i.e. the yellow spots on different sections of the abdomen) and the antennal scapes were black (i.e. the first section of the antennae, closest to the head).

I posted my thoughts on the UK Bees, Wasps and Ants Facebook group and on Twitter, and received confirmation that my ID is correct! Having looked on the NBN gateway, I can see that it is not a new species to Cambridgeshire, but it may be a new species for Cambourne. I shall dig further and find out.

Having identified the bee as N.ferruginata, I did some reading about it. Bees in the Nomada genus are commonly referred to as Nomads or ‘homeless bees’. This particular species seems to be quite a rare bee, listed as endangered in the Red Data Book but this probably needs to be revised. It is either being identified correctly more often, or actually experiencing a population increase with more records the last couple of decades (a new species for Worcestershire in 2008). It is a cleptoparasite on another solitary bee species, Andrena praecox, although one website refers a source that suggests that A.varians might also be a host species. A.praecox also seems to be quite a rare species as apparently the females are very dependent on willow catkins.

In conclusion – what I have learnt from the Nomad ID?

• That not all wicked-looking Hymenoptera are ichneumon wasps.
• That it is worth taking notice of the small, quiet insects that aren’t buzzing or fluttering about.
• That some Nomada species can be identified from photos only, but only if photos are taken from lots of angles (I could have done with more angles). However, not all of them are as there can be some slight differences that require closer examination.
• That a good field guide can make all the difference. Whilst my general insects book (Brock) led me to the correct group, the bee book (Falk) provided the technical expertise to narrow it down to the exact species.
• That it is worth pursuing identification and I shouldn’t give up on species identification just because it looks difficult! I.e. I should be more confident in myself and my ability to work through the process of identification.

Birdfair – Day One

It has taken me a couple of days to come to terms with Birdfair. And by that, I mean the sheer amount of awesomeness packed into just three days. I’m going to attempt to describe my experience of Birdfair, but I really don’t think I’ll do it justice!

Day One

I travelled up from Cambridge with Matt and Tom, who had to put up with my growing excitement. Though they were partially to blame – both of them had been to Birdfair previously and were telling me what, and who, they had seen before. Following the signs directing us to the Fair, we found the queue to get in. As naturalists we used the opportunity to look out the car windows at surrounding wildlife (no photos I’m afraid).

We drove past the shiny new Volunteer Training Centre that had be opened by Sir David Attenborough last month for the Leicestershire and Rutland Wildlife Trust. Apparently “the centre will provide support and training for volunteers in conservation, countryside and heritage skills.” I shall keep an eye on what they get up to, it sounds interesting!

And then, it was Birdfair itself and all that comes with it! We were soon bumping into familiar faces and meeting some faces who were familiar from the internet but now appearing in the real world, and the planning which events to go to across the weekend.

11.15am – Bug Walk, Brian Eversham & Ryan Clark (the Wildlife Trusts)

Prior to even arriving at Birdfair, I absolutely knew I had to go on this Bug Walk. I often talk about insects and invertebrates with Brian on Twitter, and wanted to support Ryan as this was his first Birdfair event he had assisted with (I think?). Armed with sweep nets and pots, we headed out into a nearby meadow where Brian demonstrated how to use the net before letting us loose! It wasn’t the warmest of days, but there were plenty of invertebrates to be found – spiders, ladybirds, bees, beetles and more! I haven’t labelled the species on any of my photos as Ryan is putting together a bugs at Birdfair ID quiz for A Focus On Nature.

Post-bug walk provided an opportunity to do some wandering and the beginning of working out how to decide what to buy. There was SO MUCH – whole libraries’ worth of books, optical equipment, exquisite illustrations, clothing, stunning photographs, carvings, memberships, holidays, and more! Matt and I began with a couple of books – Inglorious and Behind the Binoculars, as Mark Avery and Keith Betton were both doing signings.

1.15pm – Moth Trapping – Live on the big screen, Phil Sterling & Richard Lewington

A glance at the time and it was time to head over to the Events Marquee as moths were in the limelight (well spotlight). Phil Sterling and Richard Lewington were opening a moth trap at the front, and they had some lovely species – Dusky Thorn (Ennomos fuscantaria), Canary-shouldered Thorn (one of my favourites! Ennomos alniaria), Eyed Hawk-Moth (stunning! Smerinthus ocellata), plus some escapees (particularly the Large Yellow Underwings (Noctua pronuba), surprise surprise!).

Exiting out the side of the tent, we found the craft beer, woohoo! I’ve come across From the Notebook on social media as various naturalists excitedly tweet about beer that has wildlife on it!!!! Sadly, I still don’t like beer, but I liked the designs, and both Matt and Pete liked the beer.

 

More wanderings, including via the Butterfly Conservation stand  of course – cue a good chat with Martin Warren, Tony Davies, Douglas Boyes, and Nick Baker! I was wearing my H&M moths shirt and Nick Baker was very impressed with it, which was rather awesome. Also at the BC stand, I picked up a copy of the latest Moths Count newsletter, in which I have an article!

I also went via the Art Mural (which was being added to across the weekend) and, of course, the Children’s Art Mural that A Focus On Nature run. Just before the last event of the day, I managed to meet up with Phil Sterling. We live just around the corner from each other in Dorset, but hadn’t managed to meet up yet this year, so it was good to catch-up. He had brought some cool caterpillars along, and my query to get better lighting on them (for taking photographs) led to a bit of a gathering just outside the marquee as passerbys noticed the caterpillars!

6pm – RSPB Birders Lecture in association with British Birds

Crikey, 6pm already! Time to run over to one of the lecture marquees in order to catch the RSPB Birders Lecture in association with British Birds! Introduced by Stuart Housden (Director of RSPB Scotland), four birders were competing for the title of ‘Best ever day’. We heard from the marvellous Bill Oddie, the ever-inspirational Lucy McRobert, the wonderful Adam Rowlands and the legendary Ian Wallace. I was slightly biased towards Lucy winning of course, but was blown away by Ian Wallace’s account. He had made it into a spectacular play, which he performed with flair and style. As to be expected, he won.

A drinks reception afterwards, hosted by RSPB, provided another opportunity to chatting with fellow A Focus On Nature members, and other Birdfair attendees. I even spoke to Bill Oddie without getting too starstruck! And so, the end of the first day, and I was exhausted, bewildered and overwhelmed. What would the second day bring?
