Wrong way up and keeping warm in the icey pond
No interactions present.
There appears to be a considerable amount of mottling on the elytra. This makes me think these are N. maculata rather than N. glauca. Not familiar enough with maculata to decide. It is not unusual to see N glauca with mottled elytra but in my experience not as extreme as on this individual. I certainly dont think you can decide between the two on this photograph.
I think you have a good point. In my book I have only got glauca, but having looked at the maculata details online I think it may be the later. If I get a chance to pop out back and catch some again I will have a more detailed look
When I used to work with maculata and glauca I very rarely found maculata with the glaucus pronotum seen here, hence agreeing with glauca - it may have been genetic drift in our breeding stocks, however!
