new foodplant for Phyllonorycter leucographella (Zeller, 1850)
range of foodplants utilised by Phyllonorycter leucographella
is expanding since its discovery in 1989 in the UK.
Plant in his 'Hosts of the British Leaf-mining insect fauna'
(2005) (in prep) gives the following as the known foodplants:
Crataegus (Hawthorn), Malus (Apple), Pyracantha (Firethorn),
Pyrus communis (Pear) and Sorbus aria (Whitebeam).
Dickerson has now found P. leucographella on London Plane (Platanus
x hispanica). Because of the size of the leaf one had three mines
along its mid-rib (shown opposite) and on one of the other leaves
a mine was over the middle of one of the side veins.
They were found in October 2005 in St.Neots (Hunts, VC31).
was also present in some of the leaves.
next two photographs are also from leaves of London Plane. These
were found by Kevin Royles
Church (Hunts, VC31)
again that the blister mine is upper surface and along the
close up of the mine can be seen here. The mine of P.platani
can also be upper surface but the blister mine in this case
tends to be whiter initially and then becomes an uniform brown
colour, whereas the characteristic speckling of P.leucographella
is seen oppposite.
mine of P.platani is broader and
can also be found on any part of the leaf, upper or lower surface.
Any folds tend to run parallel along the long axis of the mine
with this miner.
further host plants are found for this (or any other miner)
then please let Colin
news of a new foodplant comes from Steve Hind and Roger Brereton
who discovered P.leucographella feeding on Beech (Fagus sylvatica)
on 18.viii.2002, in Hurdsfield, Macclesfield, Cheshire (VC58).
He says that 'The mines typically develop over a leaf vein into
the usual peardrop shape'
