Hi All,

just wondering if my tentative ID as "Calliopum sp." (by looking at pictures, as I don't own a key for these) is accurate and/or if maybe even a species name would be possible?

Netherlands, Drenthe, Ruinerwold, 2020-10-18
cf. observation at

Many thanks in advance!

Thanks Mark, I take it the images are insufficient to really decide on C. aeneum or simillimum. I just now stumbled on this thread and if the images by Andreas are not sufficient mine certainly aren't either...

Is the jizz enough for cf. aeneum or should I stick with sp.?

The genitalia need to be visible,

The jizz for aeneum is a subtle greenish sheen, but it is very subtle and not always there.
