稻水象甲Lissorhoptrus oryzophilus Kuschel（鞘翅目：水象甲科）的游泳行为与大多数其他水生象甲相比是独特的。游泳时的推进力仅由中胸腿提供。腿在前伸和后缩时同步移动。前胸腿和后胸腿充当潜水平面并提供稳定性。稻水象甲的平均游动速度为1.53（0.15 SE）cm/s，变幅为0.88 ~ 2.52 cm/s。象鼻虫平均每秒5.67（0.22 SE）次。L. oryzophilus与Phytobious leucogaster（Marsham）（= Litodactylus leucogaster）、P. comari（Herbst）、Bagous cavifrons LeConte、B. americanus LeConte和B. limosus Gyllenhal。它也不同于其他水生鞘翅目和半翅目的游泳描述。此外，L.米象在水面以下游泳，在实验室中在18.0厘米深的地方观察到。这使得自由游泳的模式（不包括滑冰）至少有3个成年水生仙茅。
The swimming behavior of the rice water weevil Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) is unique in comparison to that of most other aquatic weevils. Propulsion during swimming is provided only by the mesothoracic legs. The legs are moved synchronously during protraction and retraction. The pro- and metathoracic legs serve as diving planes and provide stability. The average rice water weevil swimming speed was 1.53 (0.15 SE) cm per s with a range of 0.88 to 2.52 cm per s. Weevils averaged 5.67 (0.22 SE) strokes per s. The mode of swimming by L. oryzophilus differs from those described for Phytobious leucogaster (Marsham) (= Litodactylus leucogaster), P. comari (Herbst), Bagous cavifrons LeConte, B. americanus LeConte and B. limosus Gyllenhal. It also differs from descriptions of swimming for other aquatic Coleoptera and Hemiptera. Furthermore, L. oryzophilus swims below the surface and was observed at depths of 18.0 cm in the laboratory. This brings the modes of free swimming (exclusive of skating) to at least 3 by adult aquatic curculionids.
