Mystery wildlife

This web page is about natural history puzzles: trying to identify species that Honeyguiders – leaders or participants – find a mystery.

A recent mystery was this larval case emailed to me from France. Very puzzling until the case's incumbent came to light - a cicada, right.

Here's the original mystery: a strange beetle in Extremadura in March 2010. It joined us at a picnic on the Belén Plain, just north of Trujillo.

This armoured beetle or weevil reminded me of another we found in Algarve in April 2009, though less elongated - pictured top right (also on this page and also in the holiday report here page 13). That armoured beetle was eventually identified as Sepidium elongatum.

Mystery weevil, Extremadura,

Neither the Algarve beast, nor this one in Extremadura, were in a book on Iberian invertebrates owned by Extremadura leader Martin Kelsey. Internet searches are another way of trying to get an ID, though that's hit and miss.

Via Honeyguide's e-newsletter, this puzzle has reached two of the UK's top entomologists. They advise that it is a weevil of the genus Brachycerus. More information remains welcome!

She lives on mainland Greece, in the Peleponnese south of Athens, and was coming to join us in Crete before volcano ash scuppered that. It's plainly a composite – daisy family – but isn't in Blamey's Mediterranean wild flowers. It was photographed on 10 April at 200-250 metres.

The leaves had a subtle onion smell and I thought it wasn't a star-of-Bethlehem (Ornithogalum) as it has all white petals, rather than tepals with a green stripe on the back. Not so, John advises: it is Ornithogalum concinnum, and looking more carefully there is a green stripe on the bud, but lost in the full flower.

This white flower was growing in small patches on small granite platforms by roadside near Trujillo. It's not a plant I recall seeing before, suggesting it's early to flower but more evident this year in a late spring.

It's not in Blamey/Grey-Wilson's Mediterranean flower book, but there is, it turns out, a black-and-white line drawing in Polunin's Iberian book that doesn't do it justice.

Weevil from Extremadura, of the genus Brachycerus. Amazingly, something very similar was found and photographed on our Central Portugal holiday in April.
