Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters.

It has a preference for alkaline ponds and lakes, sometimes weakly saline, with a water depth of 50 cm or more and a low organic matter content.

All year round.

Adults generally overwinter (although nymphs have been found overwintering in bottom mud) and oviposit in April. Egg and nymphal development takes 2 to 2.5 months and the resulting adults may give rise to a second generation. It is possible that first generation adults and second generation nymphs overwinter, but evidence for this is uncertain. C. panzeri feeds on algae and chironomid larvae.

Corixa panzeri is widely distributed in the UK, but seldom abundant.

Status in Leicestershire and Rutland not known.
