larva in the mine

full grown larva

mine

In autumn the mine begins as a brown, narrow and inconspicuous, lower-surface corridor. The larva is capable of leaving its mine and restarting elsewhere, possibly in another leaf. In April – May of the following spring a full depth transparent blotch is made, from which most frass is ejected. The mined leaf soon drops, which makes the mine even more difficult to detect (Simpson, 2004a).

notes

Bradley ea (1979a) write that also the polyphagous tortricid Ditula angustiorana occurs on Viscum, leaving “blister like” feeding traces. This description does not match well with the normal habit of the species, suggesting a possible confusion with C. woodiana. In any case, angustiorana spins some leaves together in tortricid fashion, which, if needed, may help to distinguish it from woodiana.
