Summary: Notes on the morphology of Attacus caesar Maassen, 1873 from the Philippines (Lepidoptera: Saturniidae). - Attacus caesar Maassen, 1873 (Lepidoptera: Saturniidae) is a highly variable moth, which is distributed on some of the Philippine islands. For the distribution of this taxon confirm Peigler (1989) and Nässig & Treadaway (1998). Presently no reliable records from any location outside of the Philippines are known. The female of A. caesar belongs worldwide to the largest moth. This paper particularly deals with the color variation and pattern variation in the adults of A. caesar. The moths unambiguously demonstrate a sexual dimorphism, which is mainly expressed by distinct wing shapes, distinct antennae dimensions, and much distinct shapes and sizes of wing fenestrae (hyaline areas). There are two color morphs with connecting intergrades present in each the male and the female adults. The orange color morph is the more rare morph in A. caesar, while the olive greenish morph is found very common in collections, cf. U. Paukstadt & L. H. Paukstadt (1990). In one notable intergrade the ground color of the forewings is olive greeninsh and of the hindwings reddish. Experiments stating that this color polymorphism is due to particular weather (e.g. temperature, humidity) influences which the preimaginals encountered, similar experiments were carried out and stated this for Rothschildia lebeau (Guérin-Méneville, 1868) by Janzen (1984), are still lacking for the genus Attacus Linnaeus, 1767. The range of variability in the morphology of the wing fenestrae in the male and female adults is considered being not different from those of other taxa in the genus Attacus but more variable in the males of A. caesar. Some selected distinct arrangements of fenestrae in male and female specimens of A. caesar are figured herein, covering the range of variability known thus far. This contribution based on the collection of specimens of the genera Attacus and Archaeoattacus by Laela H. Paukstadt (Wilhelmshaven, Germany), which is now preserved in coll. Museum Witt (Munich, Germany).
