Abstract

Larvae of the hemlock loopers Lambdina athasaria (Walker) from Vermont and L. fiscellaria (Guenée) from Maine are described for color, chaetotaxy, and gross morphology of the head, body, and legs. Body color varies from pale white-grey to dark green-brown with pigmented sclerotized bands. Head capsule color varies from pale grey-white to dark brown, with dark sclerotized spots of variable size. Many L. fiscellaria larvae are a lighter color than L. athasaria, but no consistent differences were found. The chaetotaxy of micro- and macrosetae conforms to the Geometridae, but the lack of detailed descriptions for other Lambdina species precludes a generic diagnosis. The homology of setae L and SV in Geometridae requires further resolution, particularly with respect to the presence or absence of L3 and SV2.

Résumé

L’auteur décrit la couleur, la chétotaxie, ainsi que la morphologie générale de la tête, du corps et des pattes des arpenteuses de la pruche Lambdina athasaria (Walker) au Vermont, et L. fiscellaria (Guenée) au Maine. La couleur du corps varie de gris-blanc pâle à vert-brun foncé avec des bandes sclérifées et pigmentées. La couleur de la capsule céphalique va de gris-blanc pâle à brun foncé, avec des taches sclérifées de dimensions variables. Plusieurs larves de L. fiscellaria sont plus pâles que celles de L. athasaria, mais ces différences ne sont pas constantes. La chétotaxie des micro- et macrosoies est conforme à celle des Geometridae, mais l’absence de descriptions détaillées d’autres espèces de Lambdina ne permet pas l’ébauche d’une diagnose du genre. L’homologie des soies L et SV chez les Geometridae n’est pas bien résolue, particulièrement en ce qui concerne la présence ou l’absence de L3 et SV2.
