Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Calluna
|
1a > Leaf-miner: The fully developed 4 mm to 5 mm case is made of seven to ten
mined heather leaves arranged in a neat herring-bone pattern. The
cases closely resemble sprigs of heather and are best found by placing
swept debris in a box, where the larvae will reveal themselves by
climbing the sides.
Very
small (c. 4 mm) light brown lobe case with a mouth angle of about
40°. The case is composed of 8-10 small leaf fragments, placed
in herringbone manner, giving the case the appearance of a small
browned ling branchlet. |

On Calluna and Erica in Britain and elsewhere. Most
parts of Britain. Also recorded in the Republic of Ireland. Widespread
in continental Europe.

Coleophora
juncicolella Stainton, 1851 [Lepidoptera: Coleophoridae]. |
1b > Leaf-miner: The
larva forms a distinctive black case from silk, from which it feeds
on the foliage or flowers of heather or bell heather. The larval
case reaches around 9 mm in length when fully fed. |

On Calluna and Erica in Britain and elsewhere. A

occurs sparsely in Ireland. Widespread in continental Europe.
