The defensive spray of the bombardier beetle Stenaptinus insignis is ejected in quick pulses (at about 500 pulses per second) rather than as a continuous stream. The pulsation may be a consequence of intermittency in the explosive chemical process that generates the spray. The ejection system of the beetle shows basic similarity to the pulse jet propulsion mechanism of the German V-1 "buzz" bomb of World War II.
投弹手甲虫（Stenaptinus insignis）的防御性喷雾是以快速脉冲（每秒约500次脉冲）的形式喷出，而不是连续的水流。这种脉动可能是产生喷雾的爆炸化学过程间歇性的结果。甲虫的喷射系统与二战时期德国V-1“嗡嗡”炸弹的脉冲喷气推进机制有基本的相似之处。
