Painting cows with zebra stripes reduces the attacks by biting flies by 50% and seems a good alternative to using insecticides (https://www.theguardian.com/world/2019/oct/11/if-the-shoo-fits-cows-painted-with-zebra-stripes-keep-flies-in-line). This work, of course, reflects attempts to determine WHY zebras have stripes. Rather than being a device to blend into the background, it appears that the pattern interrupts the motion detection systems of flying ectoparasites, making landing more difficult. Perhaps the breeders will be able to come up with striped cows, negating the need to paint?
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
