Very interesting. Fascinating actually. But I must of course question the article's claim that this insect has "evolved" to do this. There is no evidence that this is "new" behavior for the species, and even if it were new behavior, this is no qualification for having "evolved." There is no new genetic information in the species, and therefore it is either new learned behavior within the species, or else it is behavior that has always occurred and has just recently been discovered by science. Just my 2 cents on the matter. Take it or leave it.
