Pebobs is a genus of moths in the family Cosmopterigidae.
Pebobs species are very small to small moths in the family Cosmopterigidae. Forewing length of 2.9-4.3 mm. The external features are as in Cosmopterix. Wing venation with 12 veins in forewing and 7 veins in hindwing. Forewing with Sc and R1-R5 to costa; R5 stalked with M1; M1-CuA2 to termen; CuP very weak and not reaching termen; 1A+2A with basal fork, to dorsum. Hindwing Sc along costa and joining Rs at three-quarters; M1-CuA2 to termen; veins often not fully developed due to the narrow shape of the hindwing.[1]
The biology has only been described for Pebobs ipomoeae. The one known life cycle does not differ from those of the known life cycles of Cosmopterix species.
