| | | ID for a tiny green beetle
Hello,
Spotted this cute green beetle - around 0.5cm long - close to the ground on a dried up teasel head at Whitecliff Bay this afternoon.
Searching around for pics of something similar the closest I have found is the Cereal Leaf Beetle Oulema melanopus, although the detail around the head doesn't quite match with pics I've seen.
What do you think?
Thanks for looking,
Rob

It does like an Oulema. |

Oulema melanopus/rufocyanea the two species need to be dissected to tell which is which.
After thought as Aeshna says I would leave this as just Oulema the head looks different to any ive seen.

Thank you Aeshna and Dogghound, Oulema sp. will do for me,

Does look a bit odd, what about Sermylassa halensis? |

Definitely not an Oulema spp., as the shape of the body is wrong. I'd agree with lync and say it's Sermylassa halensis. |

Lync, Rossco, thank you for having a look here.
I agree - having studied more beetle pics this one is all wrong at the front end for an Oulema.
Sermylassa halensis looks good, and it is recorded here on the IoW (maybe it's common everywhere, I haven't found any info on it yet).
Previous to your suggestion I'd received another that it was a Gastrophysa polygoni, which also looked promising I thought.
Although it was on a dead teasel head other plants in the area were mainly Restharrow, Birdsfoot Trefoil, Ribwort Plantain, grasses, and small hawkbit-type composites, on an 'active' area of clay landslide - mostly bare dry ground.

You're not wrong, G. polygoni does look very similar, but take a look at the antennal segments and the shape of the pronotum, although the latter is not obvious in your pic. All these things suggest S. halensis.
