‘Pocket Guide to the Bumblebees of Great Britain and Ireland’ – Book Review (Mike LeRoy)

Mike LeRoy has written a review of a new book by Richard Lewington which was published in February:  Pocket Guide to the Bumblebees of Great Britain and Ireland (Bloomsbury 2023)

Mike says: “Bumblebees look as though they should be easy to identify, but often they are not. This new book is far better at aiding accurate identification than any I have ever used – which is many!”

The full review is can be found here: Pocket-Guide-Bumblebees-Book-Review

Learning more about bumblebees to enable you to identify them will be a good basis for then sending in your Sightings and submitting them as records.

Wild Fell by Lee Scofield: Book review by Julie Lane

Wild Fell: Fighting for nature on a Lake District hill farm
by Lee Schofield (Penguin/Doubleday, 2022)

I thought you might be interested to read the following book which gives an insight into the natural history of the area where I now live.

Lee is my son-in-law’s colleague and they both work at the RSPB’s Haweswater Reserve. Lee came to their wedding a couple of years ago and played the guitar and sang wonderfully which was a great treat. He is a humble modest man but very likeable and extremely knowledgeable about the wildlife of the Lake District.  His book is brave, poignant and ultimately hopeful.

I grew up visiting the Lake District regularly for holidays but over the years the pressures on this beautiful place have increased exponentially. Overgrazing of the fells, pollution of the lakes and also the huge numbers of tourists who visit every year have resulted in a degraded landscape with very little wildlife.

This book is an appeal and a justification for change by a man who really knows his subject. He has been working with others to trial and refine ways to run a viable upland farm in a manner that enriches the landscape in Haweswater and allows nature to creep back slowly but surely. He describes how by planting trees, re-wetting peat bogs and re-wiggling rivers they are slowly making progress. It is understandably not easy for other land managers such as farmers who have lived in the area for generations to accept these changes as a necessary movement towards a healthier more sustainable and ultimately more productive landscape. But Lee looks into the pressures they have faced and the confusing and changing political landscape they have had to contend with and is always broad minded in his writing.

This book has a serious message but is also a fascinating and enjoyable read about the wildlife to be found and the characters who work in this corner of the Lake District. I thoroughly enjoyed reading it, and alongside James Rebanks’ two books A Shepherd’s Life and English Pastoral, I think you get a very balanced view of the pressures and challenges of farming in this beautiful corner of our country as well as a lot of background as to how we have got ourselves into our present nature-depleted state.

The area is to be seeded with 70 grass and flower species and planted with native trees to create wood pasture,

My Octopus Teacher – a recommendation

A note from Julie Lane:

I would like to strongly recommend the following film to anyone who has access to Netflix. It’s called My Octopus Teacher and is an amazing documentary about a diver and photographer in South Africa who forms a relationship with a wild common octopus. It was filmed over the period of a year in a cold underwater kelp forest at a remote location in False Bay, near Cape Town.

The photography is stunning and it gives a wonderful insight into the life of the octopus and the effect it has on the man himself. Very moving and beautiful!

The beauty of flies

Stalk-eyed fly

Stalk-eyed fly

Dr Erica McAlister, of London’s Natural History Museum, talks to Jim Al-Khalili about the beautiful world of flies and the 2.5 million specimens for which she is jointly responsible.

According to Erica, a world without flies would be full of faeces and dead bodies. Unlike, for example, butterflies and moths, whose caterpillars spend their time devouring our crops and plants, fly larvae tend to help rid the world of waste materials and then, as adults, perform essential work as pollinators. Yet they are rather unloved by humans who tend to regard them as pests at best and disease vectors at worst.

2019 is international Year of the Fly, and dipterists and entomologists around the world are working to raise the profile of the many thousands of species so far known to science.

Erica tells Jim about her work in the museum, cataloguing and identifying new species either sent in from other researchers or discovered by her and her colleagues on swashbuckling trips around the world. Modern gene sequencing techniques are revealing new chapters in the life histories of species, and her collection of 300 year old dead flies continues to expand our knowledge of how the world works.

Perhaps in the future, she argues, we will all be eating pasta and bread made from fly-larvae protein, or using small tea-bag like packets of maggots in our wounds to clean out gangrenous infection.

Get Bucks Buzzing

Tree Bumblebee by Harry Appleyard, Tattenhoe 24 February 2017

Tree Bumblebee by Harry Appleyard, Tattenhoe 24 February 2017

Welcome to Bucks Buzzing, and your chance to help the insect pollinators that help all of us.

Pollinators come in a range of shapes and sizes from bumblebees to butterflies, moths, hoverflies, and of course, honey bees.

We depend on pollinators for much of our food including apples, pears, strawberries, plums, peas, beans, and for other important plants like wildflowers.

But our pollinators are falling in numbers and are in severe decline across Buckinghamshire and nationally.

Butterflies of Northamptonshire in 2018

For Northamptonshire’s butterflies 2018 has been a memorable year for many reasons. Not only did we have two national projects in the county but it was also an exceptional season for many of our butterflies. When I first became interested in the serious study of butterflies I’d often hear stories of huge groundings of Purple Hairstreaks, explosive Black Hairstreak years and numerous rare aberrations and colour forms which at the time such spectacles seemed to be confined to the history books so to witness many of these events first hand in 2018 made the year an extraordinary one to say the least.

Red-Tailed Bumblebee by Harry Appleyard, Tattenhoe 11 April 2016

Welcome to the BRITISH BEES ON FLICKR site. This collection covers nearly all 278 species of bee on the British and Irish list (including the Channel Islands) acting as a virtual field experience and virtual museum collection. Special thanks are due to the Natural History Museum, London and the Oxford University Museum for allowing me to photograph specimens that were lacking in my own collection and to other photographers for allowing me to host their images.

You may be interested in this free app, available for Apple and Android devices:

Smartphones are becoming an increasingly important part of birding. If you want to be the first person to hear about a rare bird, digiscope a rarity, or submitting your sightings, having a small portable computer at your fingertips is enabling all of this to happen. We also look to our smartphones as identification aids now that field guides are packaged into apps. But what if your app could instantly scan your photo and match it to a species based on an archive of millions of bird images? It can.

The Merlin Bird ID app was developed by the Cornell Lab of Ornithology to do just this, taking a photo you snap in the field, and suggesting an identification. Photo ID identifies birds in photos using computer vision technology trained on nearly 3 million images uploaded to Macaulay Library through eBird checklists.

The high accuracy of the Photo ID tool is largely thanks to the extensive collection of images at Macaulay Library, showing birds from many different angles. Annotations on these images (a box drawn around each bird in the photo) also help teach the Photo ID tool to find the birds in the photo–-anyone can help improve Merlin’s accuracy by adding new annotations with Macaulay’s MerlinVision tool.

Mapping wildlife for better planning

Explore the Ecological Status of Great Britain’s 10km squares.

Ecological Status is a biodiversity index developed by the Biological Records Centre from national plant and animal observations. It is calculated for each 10km square of Great Britain and is relative to the Environmental Zone that that square occurs in. An Environmental Zone is a region of broadly similar environmental characteristics and is used here to control for non-biological factors that affect biodiversity (e.g. geology and climate).

Veteran Tree Survey and Ecological History 25 June 2017

This important historical parkland of Greenwich Park, much of it on steep slopes giving stunning views across the Thames estuary (in good weather), is also the setting for an array of veteran trees. We will survey their ecology and importance as a habitat and look at the development of the parkland within its landscape.

Errors in botanical surveys

Errors in botanical surveying are a common problem. The presence of a species is easily overlooked, leading to false-absences; while misidentifications and other mistakes lead to false-positive observations. While it is common knowledge that these errors occur, there are few data that can be used to quantify and describe these errors.

Beginner’s guide to identifying British ichneumonids

What are ichneumonids?

Ichneumonids are wasps (order Hymenoptera, superfamily Ichneumonoidea) with a very narrow wasp waist between the middle (mesosoma, roughly equivalent to the thorax on other insects) and hind (metasoma, roughly equivalent to the abdomen on other insects) body parts. They have powerful chewing mandibles, two pairs of usually transparent membranous wings with complex venation and long antennae with 18 or more segments. They are invertebrates, so don’t have a backbone.

Arctic stronghold of world’s seeds flooded after permafrost melts

It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.
