Squish

Little point squashing them, individual manual efforts will not make any real difference to the population of this species in the UK.

As David says, utterly no

As David says, utterly no point squashing it - not only is there the possibility of killing a native species (although this is definitely a Harlequin), but it would make no difference to the British population.

A recent count of Harlequins in a small patch of nettles in Bedfordshire estimated 390,000 larvae, and each adult female can lay 2200 eggs, with two generations per year. Furthermore, even if every Harlequin in the UK were to keel over tomorrow, the populations in France & Belgium, along with accidental imports on produce, etc, would ensure that the south coast would be repopulated within the week.
