Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Ficaria
|
1 > Leaf-miner: A conspicuous white linear mine with frass in closely adjoining
grains. Pupation external. Puparium greyish or brown |

On Ranunculus acris, Ranunculus bulbosus, Ficaria verna (= Ranunculus ficaria),
Ranunculus flammula, Ranunculus lingua, Ranunculus repens and Ranunculus sardous in Britain and additional Ranunculus species elsewhere. Common and widespread throughout England and
Scotland in Britain. Widespread throughout Europe, ange extending
to the Kirghiz Republic of the [former] U.S.S.R. Also recorded
in Canada, Chile and Japan.

ranunculi (Schrank, 1803) [Diptera: Agromyzidae]. |
1b > Leaf-miner: Long,
upper-surface corridor with the frass in relatively large, widely
dispersed fragments. Pupation outside the mine; exit slit in lower
epidermis. |

Phytomyza ranunculivora puparium

On Ranunculus acris and Ranunculus repens, but not yet on Ficaria, in Britain and additional Ranunculus species and Ficaria verna (= Ranunculus ficaria) elsewhere. Widespread in Britain and continental Europe.

Phytomyza
ranunculivora Hering, 1932 [Diptera: Agromyzidae]. |
1b > Leaf-miner: Full depth, initially a much branched corridor, irregular in width,
in the end almost a blotch. The mine has openings by which part
of the frass is ejected. The larvae frequently leave the mine to
restart elsewhere. Older larva live free and cause window feeding,
often erasing their old mines. In Coltsfoot also pseudo-mines are
made, when the larva eats away the lower epidermis with the leaf
tissue, but spares the dense hair cover. |
On Ficaria verna (= Ranunculus ficaria), in Britain and numerous genera and species in
several families elsewhere. Distribution in Britain unknown. Widespread
in continental Europe.
