LONICERA.
Honeysuckles. [Caprifoliaceae]
|
Eighteen
species of Lonicera are recorded Lonicera.
Elsewhere
the tephritid Philophylla
caesio is recorded as a miner in the petioles of Urtica sp. by Ferrar
(1987), Beiger (1968)
and White (1988), although
there are unconfirmed records on Caprifoliaceae and Asteraceae, which seems an odd combination of hosts.
A key to the European miners recorded on Lonicera is provided in Bladmineerders van Europa. |

Note: Diptera larvae may live in a corridor mine, a corridor-blotch mine, or a blotch mine, but never in a case, a rolled or folded leaf, a tentiform mine or sandwiched between two more or less circular leaf sections in later instars. Pupation never in a cocoon. All mining Diptera larvae are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall. The larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue. In some corridor miners frass may lie in two rows on alternate sides of the mine. In order to vacate the mine the fully grown larva cuts an exit slit, which is usually semi-circular (see Liriomyza huidobrensis video). The pupa is formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

1a > Leaf-miner: Mine star shaped when small, sometimes with a longer linear section,
later an irregular brownish blotch. Pupation internal (Spencer,
1976: 466).
Mine
not associated with the midrib, stellate, with a large number of
short upper-surface corridors. The mine looks greyish and is inconspicuous.
Frass in discrete grains. One, sometimes two larvae in a mine. Pupation
within the mine.
Forms an upper surface mine which is normally blotchy. The young mine is stellate. The initial mine is purple in colour - turning brown as it ages. |

Chromatomyia
periclymeni (Meijere, 1924) [Diptera: Agromyzidae]. |
1b > Leaf-miner: Mine an irregular stellate blotch with a later linear section. Pupation
internal; firmly glued within the mine by frass (Spencer,
1976: 443).
The
mine begins with a few lower-surface corridors, radiating from one
centre that is not associated with the midrib; the corridors are
very shallow and not easy to observe. Subsequently some (rarely
only one) upper-surface, rather long and often branched corridors
are formed from the same centre. Frass mostly at one side, in pearl
chains. Pupation within the mine.
An upper surface gallery with a star-shaped start. Frass in pearl-strings. |

Widespread in south of Britain. Also recorded in the Republic
of Ireland. Widespread in much of Europe.
|
Chromatomyia
lonicerae (Robineau-Desvoidy, 1851) [Diptera: Agromyzidae]. |
1c > Leaf-miner: The
very first part of the mine is a quite inconspicuous, lower-surface
epidermal corridor, that ends upon the midrib. Then the larva bores
in the midrib, from where it makes long upper-surface corridors.
Often the latest corridor that is made is much longer than the others,
and follows the leaf outline in a loose loop. Frass in long strings at the extreme side of the mine. Pupation in the mine, in a lower-surface
puparium chamber.
Initially on the mid-rib from which there may be several short narrow galleries into the leaf. In the main gallery there may be alternate lower surface and upper surface stretches. Frass in conspicuous long streaks.
A winter form not associated with the midrib and with a mine that meanders thoughout the leaf probably represents this species. Frass in long strings at the extreme side of the mine. Pupation in the mine, in a lower-surface
puparium chamber |

Note:
The larvae of mining Coleoptera, Hymenoptera and Lepidoptera may live in a corridor mine, a corridor-blotch mine, a blotch mine, a case, a rolled or folded leaf, a tentiform mine or sandwiched between two more or less circular leaf sections in later instars. Larva may pupate in a silk cocoon. The larva may have six legs (although they may be reduced or absent), a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding). Larvae of Hymenoptera and Lepidoptera usually also have abdominal legs (see examples). Frass, if present, never in two rows. Unless feeding externally from within a case the larva usually vacates the mine by chewing an exit hole. Pupa with visible head appendages, wings and legs which lie in sheaths (see examples).
|
1a > Leaf-miner and case-bearer: The larva lives outside the mine, protected by a case, and feeds on the underlying plant tissues via a hole cut in the epidermis. From that point it eats away as much leaf tissue as it can reach without fully entering the mine. Mine does not contain frass (Coleophora species) |
2 |
1b > Leaf-miner, but not a case-bearer: The larva lives mainly inside the mine. Mine usually contains frass. In later instars the larva may live sandwiched between two more or less circular sections cut from the leaf. |
3 |
2a > Leaf-miner
and case-bearer: Lobe case. The full grown case is about 7 mm long. The mouth angle
is 0°, causing the case to lie flat on the leaf. The case is
gradually enlarged by the addition of rings that are cut out of
the epidermis. The rings become gradually larger, and stick irregularly
out of the contour of the case. The rings are cut out of the lower
epidermis of the mine. This implies that mines may have both normal,
small openings, and large ones. Compare for instance C.
violacea, that cuts rings out of the upper epidermis. The larva feeds briefly initially and again after
over wintering. It then aestivates until Autumn. It makes one case
which it enlarges by adding pieces of excised lower epidermis. |

On Cornus, Frangula, Lonicera, Rhamnus, Symphoricarpos and Viburnum in Britain and Cornus, Frangula, Lonicera,
Rhamnus, Swida, Symphoricarpos and Viburnum elsewhere.
Southern England. Widespread in continental Europe.
|
Coleophora
ahenella Heinemann, 1877 [Lepidoptera: Coleophoridae]. |
2b > Leaf-miner
and case-bearer: The larva feeds on a wide range of trees, shrubs and herbs, favouring
Rosaceae, but not exclusively. The fully developed cased larva may
be found active in October and again, after winter diapause, in
April. Cases, about 6 mm, of diapausing larvae may be found through
winter, fixed to a tree or fence post. The dorsal surface of the
case is usually covered in leaf fragments, but they can sometimes
be worn off almost smooth. The ventral surface is swollen at the
middle and has a keel, which usually bends upwards at the posterior.
The cases of C. ahenella (on Rhamnus, Frangula, Viburnum and Cornus) and C.
potentillae (case less swollen, keel not bent up, resting
position less prone) are very similar.
Brownish
lobe case that lies almost flat on the leaf, either on the upper
or on the lower side. Case widest about the middle. Ventrally there
is a distinct keel. Mouth angle 0°. Full depth mines rather
large. The flaps of cuticular tissue that serve to enlarge the case
are cut out of the upper epidermis. (contrary to C.
ahenella and C.
potentillae, that use tissue from the lower epidermis).
The removal of these tissue flaps creates holes that are much larger
than those that serve as the entrance to the mine. |

|
Alucita
hexadactyla Linnaeus, 1758 [Lepidoptera: Alucitidae]. |
3b > Leaf-miner: In the first instar the larva mines the leaves, forming short,
irregular, blotch-like mines, but in later instars it lives externally,
feeding in spun leaves and often twisting those of tender shoots. Larval head light-brown or yellowish brown, edged with black postero-laterally,
ocellar area blackish; prothoracic plate black edged with whitish
anteriorly; abdomen dull dark green; pinacula distinct, black,
sometimes brownish but with black bases to setae; anal plate large,
black (Bradley et al., 1973).
Small,
full depth mine without a definite shape; little frass. Some silk
is deposited in the mine. The larva soon leaves the mine and continues
feeding among spun leaves. |
Polyphagous. On numerous genera and species of several plant families, including Lonicera, in Britain and elsewhere. Widespread in Britain
and continental Europe. Also recorded from the Channel Is.
|
Cnephasia
incertana (Treitschke, 1835) [Lepidoptera: Tortricidae]. |
3c > Leaf-miner: Forms a large transparent blotch mine - with a central spot, where
the frass collects. This spot is usually red-brown.
Brownish,
full depth, inflated blotch, usually at the leaf margin, often with
a central brown spot. Oviposition at the leaf underside. Often 2-3
larvae in a mine. Pupation outside the mine. Pupation on the bark in a cocoon. |

3d > Leaf-miner: The
mine is large, occupying most of leaf. The lower epidermis with
several strong creases.
Lower-surface,
white, inflated tentiform mine, that may occupy the entire leaf.
The mine causes the leaf to roll lengthwise (the folds in the lower
epidermis run from leaf base to tip). Pupa in a tough, papery cocoon;
in fresh mines its colour is olive green, later it changes into
pale brown. |
