Bucculatrix albedinella (Zeller, 1839)
[Lepidoptera: Bucculatricidae]

Elm Bent-wing


Lyonetia albedinella Zeller, 1839. Isis: 216
Elachista boyerella Duponchel, 1840. Hist. Nat. Lep. Fr. 11 (8): 545, pl. 309 fig. 3.
Bucculatrix albedinella
(Zeller, 1839).


Leaf-miner: Winding full depth corridor up to 15 mm long with a long larval chamber. Black frass in a central line, broad, but leaving a clear zone at either side. Characteristically the corridor has 2-4 short, frass-free, side branches (diverticula) occurring at points where the main corridor makes a sharp turn. The first one often is interparenchymatous tissue and difficult to see; the following turns usually have opening in the lower epidermis at their end. Older larvae live free on the leaf, creating windows; the exit hole is in the underside of the leaf (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

Mining larva with a black ventral spot on each abdominal segment. Free-living larva dull green above, pale yellow laterally and ventrally with some fragmented purplish subdorsal lines (Langmaid, Porter and Collins, 2007a) (see Bladmineerders van Europa).

The larva is illustrated in British leafminers.

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

The larva pupates in an oval cocoon that, contrary to what is usual in Bucculatrix, is not ribbed lengthwise (Langmaid, Porter and Collins, 2007a) (see Bladmineerders van Europa).

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
