Thousands of fireflies flying around the garden at the moment, every night between 10 and 11pm. Their movements make for some interesting, natural light-painting patterns!

Massive number of swifts (estimated over 200 above this terrace) in urban Luxembourg (despite poor weather). π The recently rewilded PΓ©trusse stream running through the city seems to have a great positive effect on local wildlife (what used to be a narrow, concreted channel). ππ»

This is what happened - huge costs of course but so many benefits (flood prevention, connection to nature, boost to local biodiversity, better water quality downstream...) ποΈ x.com/SLeguil/status/1647327β¦

Watching the "renaturation" of the Petrusse river in Luxembourg City is so interesting. From a narrow, concrete channel built in the 1930s to a natural river course. Massive works, far from finished, but nice to see Dippers and Herons already using the new facilities! π¦

Apart from trees (a substantial number along the "old" route had to be felled as they would have sat in the new river bed), there has been no planting - flora is allowed to recolonise. From brownfield annuals we are now seeing after a few months sedges & water plants appear...

Brings back memories of sleeping in an open dormitory in the middle of the Borneo forest and waking up to the sound of panicked tourists as the mosquito nets were full of giant moths and cicadas. What great fun I had moving them outside π€

Observing a few moths. Documented almost 600 species over 4 nights, excluding other invertebrates that I spent time with.
Meshed jacket was to prevent the moths from getting into my eyes, nose and ears.

I haven't (yet) left Twitter, but you can find me on my another account @sleguilfr, which makes more sense as I am now mainly working in France π«π· and Luxembourg π±πΊ. An opportunity to practice your French! π

Mind blown. The new exhibition about wild orchids of Luxembourg at @naturmusee features these incredible silicon models by German artist Sebastian Brandt, complete with dry edges, variable markings and insect damage. A great way to study orchids in 3D!

A few more of Sebastian Brandt's orchid models exhibited at @naturmusee , because I just can't resist... especially the fabulous ghost orchid with roots and leaf litter.

Green tram lines are the perfect way to get more biodiversity at the heart of a city. Here in Luxembourg π±πΊ, they are filled with native plants, benefitting insects and birds, and making an otherwise boring linear attractive for us too.

Unusually cool and wet weather on my @naturetrektours trip to the Vercors π«π· but the flora is certainly delivering, particularly orchids (my favourite, the Drome ophrys) and gentians. Large-flowered Butterwort was a treat today!

Visiting Nantes and its converted Shipyard park. So refreshing to see a place where industrial heritage, ornamental plants and spontaneous flora are all allowed to express themselves. Resilient, intelligent landscape design. Such a missed opportunity for @BatterseaPwrStn imo...π

Is anyone honestly still wondering why biodiversity is crashing in the UK? When a hedge separating a village road and a cycling path "cannot be allowed" to grow above 0.6m, you have to wonder what we've become as a civilisation...

Cannot wait for flora and fauna to establish in the new river bed, I suspect it will be interesting...the valley all around, despite its urban nature, is already quite rich: x.com/SLeguil/status/1382432β¦

Love the fact that Luxembourg city is built on huge sandstone rocks. Makes for cool urban botanising! Arabidopsis arenosa (Sand rock-cress), Hieracium murorum (Wall hawkweed), lots of ferns (nice to see Brittle-Bladder!) etc.
Ready to go on the new @inaturalist.lu platform π

London friends! Looking for something to do next weekend? Head to Surrey Quays and take part in "serious games" about biodiversity, circular economy, soils or sustainability in cities. 3h fun workshops for only Β£5 & opportunities to talk with experts: climateclarity.co.uk/earth-dβ¦ πΏ

First moths of the season here. The distinctive Brindled Beauty, the slightly bland Sloe Carpet and the ever beautiful Streamer, all three feeding on hedgerow plants such as Blackthorn, Dog rose or Hawthorn π¦

Feeling heartbroken. My village has just announced major cuts from Monday (!) in the forest plot (actually part of a @Natura2000FR reserve) that's home to breeding Eagle Owl, Black Woodpecker or Wildcat, obviously in breach of Habitats Directive. Biodiversity? Who cares... π
