Hello,

Found on the North coast of Brittany (France), last summer. I think C. Cautum but I am not sure.
Thanks in advance,

Marie-Christine

Thank you Lukasz. What makes the difference between C. cautum and C. elegans?

Greetings,
Marie-Christine

Ch. cautum
- hairs on the abdomen longer than in Ch. elegans
- abdomen more broad than in Ch. elegans
- generally yellowish species

Ch. elegans
- hairs on the abdomen very short
- abdomen more slender than in Ch. cautum
- generally blackish species.

Markings on the abdomen are really differentSmile
For more look in some key..
