Extract

The host of this gregarine is the larva of a Ceratopogonid: Dasyhelea obscura Winnertz, which, as I have previously mentioned, lives in the decomposed sap filling the infected wounds of the Elm and Horse-chestnut trees in Cambridge (at Newnham and along the Queen's Road). The parasitised larvae were found late in the season, about the end of September, they were all young and never heavily infected, containing from three to eight and exceptionally twelve parasites in different developmental stages. The gregarine seems to be rare as among several hundred of these larvae examined only twelve yielded this interesting parasite.
