POLYCARPON.
Four-leaved Allseed. [Caryophyllaceae]
|
Four-leaved
Allseed (P. tetraphyllum) is the only species of Polycarpon
recorded in Britain. It is an introduced species.
Only one British miner is recorded on Polycarpon.
A key to the European miners recorded on Polycarpon is provided in Bladmineerders van Europa.

1 > Leaf-miner: The
mine starts as a long, narrow, winding corridor running towards
the midrib, widening to a blotch. Usually upper-surface, but in
small leaves also full-depth parts may occur. The blotch has broad
lobes; in their ends most frass is accumulated in the form of green
patches or clouds. Sometimes several larvae share mine. Pupation
usually in the soil, less often in the leaf (and then generally
not in the mine itself but in a small separated mine, that may even
be made in the petiole). |
