The identity and immature stages of Patagoniodes farinaria (Turner) comb. n. (Lepidoptera: Pyralidae: Phycitinae) in Australia and New Zealand

The morphology of the immature stages and adult moth of the bivoltine blue stem borer, Patagoniodes farinaria (Turner) comb. n., is described and figured. Moths from eastern Australia and New Zealand appear to be conspecific and the species appears not to be introduced from Europe where related phycitines of similar biology occur. The blue stem borer exhibits features atypical of Homoeosoma Curtis, in which it was originally described, and generally conforms with Patagoniodes Roesler, to which it is here referred. Larvae develop in the stems of introduced ragwort, Senecio jacobaea L., and the native Senecio lautus Sol. ex Willd. (sens. lat.). Copyright © 1987, Wiley Blackwell. All rights reserved
