The study of various external features of the organism is knownas morphology. As a result, encounters with these harmless insects occur on a regular basis. But morphology is basically gratuitous, as well as complex and irregular: anything that a language does with morphology, it usually can also do more straightforwardly with syntax; and there is always some other language that does the same thing with syntax. Wastes accumulated by larvae are excreted just before the insect emerges as an adult.
