Vampire Butterflies Attack!

Swedes bring out the garlic as vampire butterflies descend on Uppland.

The blood sucking creatures originate in Asia but have gradually been moving west. This is the first time they have been spotted in Sweden.

The so-called vampire butterflies can have a wingspan of up to 45 mm and get their name from their diet of mammal blood which the males suck up through their long snout.

Insect expert Jan-Olov Björklund told TT news agency that people should not be alarmed if they come across a vampire. They normally eat fruit and plants, he says, blood is more of a delicacy to them.
