In 2003, two little girls in Toronto decided to collect insects for a summer project. One day when their dad as at work, he spied an interesting looking beetle and brought it home. They tried, without success, to identify the beetle before contacting an Entomologist on the internet, who identified it as the Asian long-horned beetle, an invasive species.
An aggressive program was launched to contain the beetle. A regulated zone was set up, and within that 30 000 trees were cut down and burnt. It was illegal to move wood from susceptible species out of the regulated zone.
I was teaching at a school within the regulated zone at the time, and they sent out fridge magnets for every kid at every school within the zone, with a picture of the beetle, and a 1-800 number to call if they saw one.
The last sighting of the Asian Long Horn Beetle in Canada was in 2007, so it has now been declared eradicated.
