![]() ![]() (2) Decreased visibility in twilight 1, 7, 8, 10, 11, 12: At dusk and dawn or in moonshine, stripes might be difficult to discern. The main hypotheses are the following 5, 6: (1) Apparent size increase 6, 7, 8, 9: The stripes could induce a visual illusion increasing the apparent size of zebras and could ensure an advantage over their predators. Since the debate among Galton 1, Wallace 2, 3 and Darwin 4 between the 1850’s and 1870’s, multiple ideas have been proposed for possible functions of zebra stripes. ![]() To eliminate this risk, a good evolutionary strategy was the avoidance of striped (and spotted) host animals. The frequent false vessel locations at the numerous black–white borderlines, the subsequent painful bitings with unsuccessful blood-sucking attempts and the host’s fly-repellent reactions enhance considerably the chance that horseflies cannot evade host responses and are swatted by them. This is consistent with the flies’ well-documented attraction to warmer temperatures and provides indirect support for the proposed hypothesis. This is because the black stripes are warmer than the surrounding grey areas in the sun, but not in the shade. ![]() We found that horseflies spend more time walking on thin black stripes than surrounding grey areas as expected by chance, but only when the substrate is sunlit. To test this hypothesis, we performed a field experiment with tabanids walking on a host-imitating grey test target with vessel-mimicking thin black stripes which were slightly warmer than their grey surroundings in sunshine, while under shady conditions both areas had practically the same temperature as demonstrated by thermography. We propose here a plausible hypothesis why biting horseflies avoid host animals with striped pelages: in sunshine the temperature gradients of the skin above the slightly warmer blood vessels are difficult to distinguish from the temperature gradients induced by the hairs at the borderlines of warmer black and cooler white stripes. The most thoroughly experimentally supported advantage of zebra stripes is their visual unattractiveness to horseflies (tabanids) and tsetse flies. Making sure you keep your rugs clean is the first step to proper house cleaning care.Multiple hypotheses have been proposed for possible functions of zebra stripes. With gentle, circular motions, wipe the stain away. Squeeze out 95% of the bubble bath water. In a medium bowl, soak a microfibre cloth in warm water and one or two tiny drops of gentle dishwashing soap or baby shampoo. Don’t be scared to wash hide it is a natural fabric. Remove all moisture before starting to wash the problem area. PRO TIP: If wine, fruit punch or even milk gets spilled on your zebra hide, gallop at lightning speed! Soak up liquid with rags, microfibre cloths, paper towels and any and all drying fibres you can find. Ideally, brush the zebra hide monthly so it doesn’t get flat and dull. Hardware stores, antique rug boutiques and even the dollar store sells very soft brushes. Once in a while, you will need to brush the hide. Your zebra hide ottoman, stool and rug do need some TLC. This DIY version isn’t sucking dust and debris into the vacuum, so wipe the panty-hosed end with a microfibre cloth every few minutes. ![]() If you don’t have a soft brush attachment, attach pantyhose to the end of the vacuum wand. To dislodge crumbs and other dried debris, squish the matter with your fingers. You will need a soft brush attachment to vacuum your zebra hide furniture and/or rug. Wondering how to extend the life of the zebra hide ottoman and footstool your globetrotting Aunt just left you? Read on! Vacuum Treatment Some people are rich in love, others rich in money, and then there’s the people rich in inherited oddities like zebra hide furnishings. ![]()
