Mine: Summer and Autumn Notes: Forms a long narrow greenish mine. The puparium is white and forms at the end of the mine, underneath the leaf. The adult was reared and emerged 13.viii.2017. A common and widespread miner. These mines are identical to those of P.autumnalis and can only be separated by larval and puparium features. The puparium of P.spinaciae is white whereas P.autumnalis is black - of course, P.spinaciae could be parasitised causing it to blacken. So recording P.autumnalis based on a black puparium isn’t safe, so it is best to rear. P.autumnalis mines occur in October and November, so there may be some overlap with P.spinaciae Data: 07.viii.2017, Hessle,South-east Yorkshire, VC61 Image:© Barry Warrington Recording Grade: 4 References: |
