Why these pretty trees smell
This picture was taken today outside of my apartment in Wilmington, North Carolina. The Bradford Pear (Pyrus calleryana) tree is a very pretty tree that is commonly planted to beautify cities. It is actually not native to America but people started planting them around cities because they can withstand harsh conditions and are very hard to kill. All trees have special traits such as smell or color to attract certain pollinators. You might have noticed that these trees have a very raunchy smell that smells like rotting fish. This is because the tree evolved this smell in order to do two things. One thing this smell accomplishes is that the smell of rotting flesh attracts its main pollinator, the blowfly (Calliphoridae), a carnivorous insect that likes rotting flesh. Another thing this smell might accomplish is that it repels insects that might come to steal the tree's nectar. So even though we might cringe as we walk past these beautiful trees, just know it's for a good cause.
