Stenostola ferrea Classification Family Cerambycidae > Subfamily Lamiinae > Tribe Saperdini > Genus Stenostola Diagnostic Features of Larvae Mature larva. As the following characters show, this larva conforms more closely to the characteristics of the Saperdini rather than to those of the Phytoeciini (in which it has been placed on adult characters). Head depressed, with sides subparallel and broadly rounded at base. Gular region with one or two setae on each side. Clypeus setose. Mentum not distinct from submentum. Prothorax with sublateral impression semicircular and pale. Abdomen with ampullae coarsely asperate, and with two transverse furrows. Pleural tubercle with several setae. Spiracles with peritreme broadly oval. It may be distinguished from larvae of Saperda spp. as follows. Head with pigmented spot of ocellus very distinct. Prothorax with pronotum horizontal. Posterior part of eusternum not asperate. Abdomen with each dorsal ampulla with a transverse row of widely separated asperities on each side of each of the two transverse furrows (i.e. four distinct rows in all, although occasionally there may be one or two additional incomplete rows present); each asperity pointed and spine-like.
