An insect trap in a tree in St Louis, Missouri, USA. The trap is designed to catch the emerald ash borer beetle, which can kill all species of ash tree. The trap is coated with a non-toxic glue and baited with oil from a Manuka tree, which attracts the beetle, and coloured purple because it is attracted more to red and purple hues. | |
