Thrips’ aquatic secrets
Some aquatic and semi-aquatic insects are adapted to climb the meniscus without difficulty, however, most terrestrial insects are unable to ascend this slippery slope. We discovered that Western Flower Thrips, which are millimeter-size flying insects, can effectively ascend the meniscus by arching their water-repellent bodies and performing spin maneuvers to gain a favorable climbing position. Furthermore, we demonstrated that thrips climbing performance vary inversely with fluid viscosity.
