The genus Hippodamia has recently been cut up into various different genera, each with subgenera. Hippodamia undecimnotata is now called Ceratomegilla (Ceratomegilla) undecimnotata.
This series is the result of a batch of larvae kindly sent to me in 2017 from Germany by Burkhard Hinnersmann (thanks!), hence these images were taken at my home in the Netherlands but:
THESE ARE GERMAN SPECIMEN - AT THE TIME, THIS SPECIES DID NOT NATURALLY OCCUR IN THE NETHERLANDS (but it has arrived in the meantime)
The individual variability in the appearance of the larvae is quite stunning - in most Ladybird species the larvae are quite constant (except for differences between the various larval stages of course):
Just for fun and comparison a side-by-side with the larva of the very common 7-spotted ladybird:
After pupating most pupae were attached to the sides of the boxes, this one I could lift out to take nicer pictures:
As with most "Hippodamia" (s.l.) the beetles can be quite variable in the development of their spots, with spots being larger, smaller or even missing. There is a spot on the lateral margin that is often quite subtle. When it is barely visible the pattern on the beetle starts to look a lot like the common 7-spot:
Here is what it looks like when it's larger:
The head patterns also vary. I have a gut-feeling that this may well be sexual dimorphism (with the black head being the ladies), but I need to get this confirmed still:
Ceratomegilla undecimnotata is the currently valid name for the Ladybird still known to most as Hippodamia undecimnotata a species of black-spotted lady beetles belonging to the family Coccinellidae, subfamily Coccinellinae.
