2-spot Ladybird

Is the 2-spot Ladybird tending to be pushed to more peripheral locations under pressure from the Harlequin Ladybird?

Interesting question

There is certainly evidence that the 2-spot is suffering as a result of the presence of Harlequins. Not seen anything that suggests its range is changing (rather than just its population declining) but I've not researched this in detail.

For my part -

I couldn't say. I have only seen one Harlequin locally, though I keep looking for others.
