The prey-predator relationship between Sympetrum frequens nymphs and Anopheles sinensis larvae in rice fields was investigated in the suburbs of Omiya City in Japan during the period from June to July of 1978 and 1980. Sym. frequens developed into 5th-9th instar nymphs at the beginning of June, and they emerged by the beginning of July after developing into the 10th (and final) instar stage.
