[Tutt] Aethes williana Larva Wild Carrot, Daucus carota January to March, October to December The larva feeds in the autumn and winter in the stems, eating out the pith and filling the space with frass, still feeding on the dead stems or working back through the frass as late as April and spinning a very slight brownish cocoon in the tightly packed mass of frass in the stem, the moth emerging in June. [Tutt] Aethes williana Larva Wild Carrot, Daucus carota January to mid March Roots should be collected in the winter months for the larvae. [Tutt] Agonopterix assimilella Larva Broom, Cytisus scoparius February to March Bushes of the foodplant, frequently found by the rides in woods, etc., will have some of their twigs joined together by a slight web; on pulling them apart the brown larvae will be found. [Tutt] Aristotelia brizella Larva Thrift, Armeria maritima Limonium vulgare February to March The larvae winter in the flower-heads, changing to pupa in April (Schmid). [Meyrick notes larvae as occurring in June-July and again in September-October.] [Tutt] Batia unitella Larva elms, Ulmus spp. February to April Under the loose bark of elm-posts and the rails by the side of fields, etc., the dirty blackish larvae may be found living under a slight web, mixed with frass and gnawed wood (Elisha). [Tutt] Biselachista cinereopunctella Larva Glaucous Sedge, Carex glauca February to March The beautiful red-spotted larva mines down the leaves in the spring, having apparently wintered in the withered tip of the leaf; it is full-fed in March and almost immediately it quits the mine it fixes itself in the angle of the leaf, and changes to a pupa. [Tutt] Blastodacna atra Larva apple, Malus spp. February to March In early spring sickly-looking buds should be pulled of apple-trees in order to obtain the larvae. The larva mines into the bud in autumn, and in winter is to be found in the alburnum of the bearing spur of the apple. [Tutt] Bryotropha affinis Larva Moss January to March, December The larva are to be found feeding on mosses growing on walls, etc. [Tutt] Capperia britanniodactyla Larva Wood-sage, Teucrium scorodonia January to March The larvae hibernate on the underside of the leaves and have at this time the appearance of little oval tufts of whitish hair. [Tutt] Carcina quercana Larva brambles, Rubus spp. January to March Look for windowing on bramble leaves, with a white silken web on underside of leaf [J Langmaid per R Edmunds] Caryocolum tricolorella Larva Greater Stitchwort, Stellaria holostea February to April Larvae should be sought in spun-together tops of the foodplant. [Tutt] Catoptria falsella Larva Moss January to mid March The larvae feed on and among the moss growing on walls, rocks, etc. [Tutt] Cochylidia rupicola Larva Hemp-agrimony, Eupatorium cannabinum February to March Old and prostrate stems may be gathered for a supply of this species. The stems should be kept out of doors, or any larvae they contain may otherwise perish. [Tutt] Cochylis atricapitana Larva Common Ragwort, Senecio jacobaea January to February Roots dug during the winter will give larvae. [Tutt] Cochylis atricapitana Larva Common Ragwort, Senecio jacobaea February to April The distorted dry stems may be collected in spring for larvae, which live thereon throughout the autumn and winter. Some spin up and pupate within the burrow; others, however, leave the stem to spin up elsewhere. [Tutt] Cochylis roseana Larva Teasel, Dispacus fullonum January to April, December Collect the seedheads of teasel and keep in a box; you will breed plenty of the adults. [Tutt] Coleophora badiipennella Larva elms, Ulmus spp. January to early February, late November to December The cases may be found throughout the winter on the lower twigs of elm-trees and the upper twigs of elm-bushes. The particular elms may be noted and the larvae gathered in spring. [Tutt] Coleophora solitariella Larva Greater Stitchwort, Stellaria holostea February to May On the underside of the leaves of the foodplant, the slender larval cases will be found, the larvae having recommenced feeding after their long hibernation (Elisha). [Tutt] Commophila aeneana Larva Common Ragwort, Senecio jacobaea February Pull gently the last year's flower-stalks of ragwort, and you will find that when the root contains a larva the stem breaks off readily, leaving a piece about two inches high, which is slightly webbed over the hole that leads down to the root. Dig up the roots, plant in pots or boxes, and bring indoors in May. [Tutt] Cosmiotes stabilella Larva bents, Agrostis spp. Festuca arundinacea February to May, July The larvae mine the leaves of the foodplant growing on chalk, and may be found in February in the brown withered tips of the leaves, from which they make pale yellow mines to the stem, pupating in April at the base of the blade, under an oval-shaped web (Warren). [Tutt] Cydia strobilella Larva spruces, Picea spp. January to February Search the ground under spruce fir-trees for mis-shapen cones, for it is these only that contain the larvae (Elisha). [Tutt] Dahlica inconspicuella Larva Lichens February to March The cases on lichen-covered tree-trunks, fences, etc., should be collected as soon as they are ready for pupation. [Tutt] Dichrorampha alpinana Larva Tansy, Tanacetum vulgare January to mid March Roots dug during the winter will give adults later in the year. [Tutt] Elachista obliquella Larva grasses, Gramineae January to March Coarse grasses growing by hedgesides sometimes show very evident signs of mining; these mines usually contain the dark green larvae of this species (Elisha). [Tutt] Elachista rufocinerea Larva Creeping Soft-grass, Holcus mollis February to March The larvae are to be found abundantly in the leaves of those plants which grow under hedges and by the sides of ditches; making broad-whitish mines, in which there is very little excrement.
