The geometrid moth Drepanogynis insciata was only known from two historical specimens collected before 1879. Now, it has been rediscovered in South Africa's Western Cape.

Veel succes maar weet dat de soort in O-Vlaanderen erg beperkt is. Echte populaties zijn gekend uit het Z van de prov, er is 1 lichtvangst in Ursel. Zoeken met de zaklamp langs oude hagen is vaak effectiever om ze te vinden.

A lepi a day keeps troubles away!
It's freezing here now but next week night temp will rise to +5°C so maybe this one will start to get active!
Theria primaria is active mainly in jan-feb, females are flightless with reduced wings, they need black- & hawthorn hedges. Local in Flanders.

“We cannot withdraw from the fact that over 1 million species of plants and animals face extinction.”

IPBES remains committed to its mandate to provide the most credible science and evidence about biodiversity to all decision makers and actors.

Left side contains a statement from Dr David Obura, IPBES Chair, regarding the US withdrawal from IPBES and extinction threats to over 1 million species. Right side shows a photograph of a man wearing glasses, dressed in a dark jacket and grey shirt, seated at a conference table with a microphone. The IPBES logo appears at the bottom with the tagline "Science and Policy for People and Nature". The design features white typography on the dark green background, creating a professional contrast. Several small pins or badges are visible on the speaker's jacket.

A new study finds significant biodiversity loss in spiders & insects including butterflies and beetles. The likely culprit is long-term changes to the El Niño cycle, fuelled by climate change.

Climate-fuelled El Niño events are devastating butterflies, beetles and other tropical insects
The research suggests the life-support system underpinning the tropics is at serious risk in a warmer world.

In 2016 we found Nevada grayling still relatively easy at Puerto de la Ragua, E of Sierra Nevada. New research shows this is one of only 4 remaining locations for this species (of once 11). It was only discovered <100y ago, let's make sure this species action plan gives it a few more 100y to live!

Het vrouwtje (met het achterlijf in de lucht) is inderdaad een groot koolwitje maar het mannetje (in de vlucht) is een klein koolwitje (met middenstip en zwart van topvlek beperkt) ;-)
Dat achterlijf in de lucht is een signaal dat het vrouwtje geen zin heeft in paren.

A new study has revealed that even modest levels of road traffic across Iceland's lowlands can significantly reduce the abundance of breeding birds, including globally important populations of waders:
Small roads, big impacts: breeding birds fall by 20% near Icelandic thoroughfares
New research reveals that low-traffic roads in Iceland reduce breeding bird abundance by up to 20% within 200 m of the road edge, with Whimbrel, Golden Plover, Dunlin and Meadow Pipit being the most-affected species.
