LASERPITIUM.
Broad-leaved Sermountain. [Apiaceae]
|
Only
one species of Laserpitium, the introduced Broad-leaved Sermountain
(L. latifolium) is recorded in Britain.
Four British miners are recorded on Laserpitium.
A key to the European miners recorded on Laserpitium is provided in Bladmineerders van Europa. |
Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Laserpitium
|
1a > Leaf-miner: A
regular greenish inter-parenchymal blotch mine, frequently delimited
by two veins, appearing somewhat mottled as a result of small deeper
areas of feeding through the upper parenchyma (Spencer, 1972b: 78 (fig. 259); Spencer,
1976: 428, 429 (fig. 748).
The
mine starts with a quite inconspicuous lower-surface corridor that
soon changes into an extensive interparenchymatous blotch. The upper
cell layer of the palisade parenchyma is eaten away in many places,
giving the mine in transparency a perforated appearance. Fresh mines
are pale green, later they turn brown; they give the leaves a strikingly
diseased impression. Feeding lines absent, frass grains strikingly
few. Larvae solitary. Pupation outside the mine, exit slit in lower
epidermis.
Forms a blotch mine between two veins, having a characteristic sieve-like appearance (where the larva has fed through the upper parenchyma). Pupation outside the mine.. |

On Heracleum, but not yet on Laserpitium, in Britain and on Heracleum, ? Angelica, ? Caucalis, Laser, ? Laserpitium, Pastinaca, Peucedanum, Pimpinella and ? Seseli elsewhere. Widespread in Britain and continental Europe. Also
recorded in the Republic of Ireland.

Phytomyza
heracleana Hering, 1937 [Diptera:
Agromyzidae]. |
1b > Leaf-miner: Larva
forms an upper surface primary blotch with several larvae feeding
together; the blotch is greenish when fresh but becomes yellowish
with age (Spencer, 1972b:
78 (fig. 257); Spencer, 1976:
376, 377 (fig. 655)).
Round or oval blotch, green at first, later yellowish. Young mine are interparenchymatous, only the older mines are truly full depth. Generally several larvae in a communal mine. Pupation outside the mine. Exit slit in lower epidermis.
A conspicuous, yellowish, almost circular upper surface blotch. Normally several mines on a leaf which may run together giving the impression of a single mine. |

Phytomyza angelicae puparium, dorsal

On Aegopodium and Angelica, but not yet on Laserpitium, in Britain and elsewhere
and Laserpitium elsewhere. Widespread throughout Britain
and continental Europe. Also recorded in U.S.A. and Canada.
|
Phytomyza
angelicae Kaltenbach, 1872 [Diptera: Agromyzidae]. |
1c > Leaf-miner: A large blotch, yellow or brown, preceded by a short,
in the end mostly unrecognisable corridor. Generally several larvae
in the mine. Especially in fresh mines the green primary and feeding
lines area well marked. Pupation outside the mine. |
On Angelica and possibly Arctium and Heracleum, but not yet on Laserpitium, in Britain. On Aegopodium, Angelica, Laserpitium and Pimpinella elsewhere. Widespread but very rare in Britain. Also recorded
in the Republic of Ireland and throughout continental Europe, except in the
south.
|
Cryptaciura
rotundiventris (Fallén, 1814) [Diptera: Tephritidae]. |
1d > Leaf-miner: A large blotch, yellow or brown, preceded by a short
corridor that in the end mostly is completely overrun. Generally
several larvae share a mine. Especially in fresh mines the green
primary and secondary feeding lines are well visible. Pupation outside
the mine. Puparium yellow. |

Euleia heraclei pupariria

Polyphagous. On numerous genera of Apiaceae and possibly some Asteraceae, but not yet on Laserpitium, in Britain
and elsewhere. Throughout the British Isles. Also recorded in
the Republic of Ireland and most of the Palaearctic region, as
far east as Afghanistan.
