Sphaeroderma testaceum (Fabricius, 1775) [Coleoptera : Chrysomelidae]


Sphaeroderma testaceum (Fabricius, 1775)


Leaf-miner: Long corridor, often following the leaf margin, with little frass and with the sides irrregularly eaten out. The first part of the corridor is full depth and makes a few close loops; the later part is more upper-surface and rather wide. Primary feeding lines often conspicuous. No morphological differences are known between the larva of S. rubidum and S. testaceum (Steinhausen, 1994a). However, there is a phenological difference: the larva of testaceum hibernates in the mine and continues feeding after winter; S. rubidum vacates the mine before winter and pupates in the soil. Hering (1957a) suggests that the identification of the beetles is an easy matter, but that is contradicted by Warchalowski (2003a). (Bladmineerders van Europa)

Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).

According to Cox (2007a) both S. rubidum and S. testaceum hibernate as larvae! (Bladmineerders van Europa)

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