Sphaeroderma rubidum (Graells, 1858) [Coleoptera : Chrysomelidae]


Argopus rubidum Graells, 1858
Sphaeroderma rubidum (Graells, 1858)


Leaf-miner: Long corridor mine, without obvious relation with the leaf margin, with little frass and irregularly eaten out sides. The first part of the mine is full depth and makes a few close loops; the second part is upper-surface and considerably wider. Primary feedings lines often obvious. The larva is so broad that is completely fills the mine. No morphological differences are known between the larvae of S. rubidum and those of S. testaceum (Steinhausen, 1994a). The larva leaves the mine to pupate in the soil (the larva of testaceum hibernates in the mine.) Hering (1957a) suggests that the imagines are easily separated, but this 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).
