Denmark’s admirals and monarchs can add a new relative to their numbers this summer – the Lesser Purple Emperor – which although relatively widespread in the rest of Europe, has not previously been a resident of Denmark.

Probably carried by the wind from countries south, the impressive blue and orange mottled butterfly has now been registered as a new species in Denmark to add to the 98 that are more common in Danish gardens and habitats.

Also known by its Latin name of Apertura ilia, a single specimen was discovered last year tryng to latch on to a population of Apertura iris or Purple Emperor. Having been snubbed by its cousin, it appears mates were called in to ride the winds from Poland and the Lesser Purple Emperor has started its own colony in Amager.

Warmer winter and summer temperatures appear to have improved conditions for the butterfly, which has been prevalent in more southern climes.

“Denmark will gradually see more southern species that are able to move easily,” says Aarhus University Biology Professor Jens-Christian Svenning.

Svenning adds that the warmer temperatures will also be making Denmark a better habitat for the Butterfly Bush or buddleja - which has a magnetic attraction for butterflies.
