Both larvae of Myrmeleon formicarius and M. bore are common antlions that make a conical pit on the dry sand. Body size of the former is larger than the latter and it is said that M. formicarius is semivoltine while M. bore is univoltine. Since antlion larvae seldom relocate their pits, prey consumption of them possibly varies among individuals. To clarify how the variation of prey consumption affects their life cycles, third instar larvae of M. formicarius were reared under various feeding conditions. All larvae reached adult stage in the second year from their egg-hatching, although it has been said that M. formicarius needs at least two years to complete one generation because the third instar larva must experience a short day length after having experienced a long day length in order to form a cocoon. This experiment demonstrated that M. formicarius can potentially become univoltine if the larva has grown under a good feeding condition. Moreover it was shown that the difference of feeding rate caused a variation in adult size but their periods of the final instar stage were nearly constant. As a result the adult eclosion was synchronous.
