| | | Pattern variability of Harlequin Ladybirds
We tend to think of three pattern variants in UK - which are very variable within themselves (  ). The non-melanic succinea form can have between 0 and 25 (maybe more?) black spots on red background. I don't think we've had a picture of an absolutely spotless one before so have posted this one from my good friend Les Wilson:  |

| | | Strange bedfellows Re: Harlequin Ladybirds
We go on a lot about Harmonia axyridis eating other ladybirds but 'adult' ladybirds, imagines, will seldom attack another imago, whatever the species. 
Another photo by Les Wilson: of 7-spot and 'harlequin' ladybird "hibernating" together .... |

What's perhaps most interesting is that the two individuals are about the same size - means nothing really but, along with many, other observations suggests that the average body size of haxy in this country has shrunk! Presumably for lack of food .... Quote:

Could be lack of sun rays as well
Considering I saw alot of larva I must say I have not seen any adults about ! |

The national 'harlequin' distribution map has been up-dated: http://www.harlequin-survey.org/imag...24July2007.jpg
Crossed the Tees (I think) and approaching Cumbria but still not reached Scotland! |

A possible natural enemy of the 'harlequin'?
A note in the recent Bulletin of the Amateur Entomologists' Society by Majerus et al notes haxy mating with 2-spots and also the possibility that this could lead to spread of the parasitic mite Coccipolipus hippodamiae which could seriously stunt reproduction of the invader ..... but rather double-edged: it wouldn't do much for the 2-spot or other native species .... | | | |
