Meniscus climbing using a fixed body posture has been well documented for
various aquatic and neustonic insects, but is not known from small flying
insects that inadvertently become trapped on water surfaces. Here, we show
that thrips (order Thysanoptera) can ascend a meniscus by arching their
non-wetting bodies to translate head-first and upward along a water
surface; if initially oriented backwards, they can turn by 180° to ascend
head-first, and climb upward on a surrounding boundary. Using
variable-concentration sucrose solutions, we show that translational and
climbing speeds during meniscus ascent vary inversely with fluid
viscosity. Becoming trapped in water is a frequent event for flying
insects, and given that most of them are very small, dedicated behaviours
to escape water may be commonplace among pterygotes.
