Probably from an Aramaic term, as well as يَرَقَان (yaraqān, “mildew; larvae”), since caterpillars aren’t swift like the root س ر ع (s-r-ʕ) means but slippery or viscous what שׁ־ר־ע / ܫ-ܪ-ܥ (š-r-ʿ) means, and the prefigation of ya- is more likely in Aramaic in general, plus the vocalization variation bolsters the suspicion.
يَسْرُوع or يُسْرُوع • (yasrūʕ or yusrūʕ) m (collective or singulative; if the former then rarely forms يَسْرُوعَة (yasrūʕa) as a singulative which can also be considered as a base form with plural يَسْرُوعَات (yasrūʕāt), if the latter then forms a plural يَسَارِيع (yasārīʕ) also vocalized يُسَارِيع (yusārīʕ))
