The Chorionic Sculpture of the Eggs of Some Xyleninae (Lepidoptera, Noctuidae)
Eggs of sixteen species of fifteen genera of the subfamily Xyleninae occurring in Ukraine are described and illustrated with scanning electron microphotographs. The diagnostic characters of the genera and species are se-lected.
Formation of Pattern and Diagnostic Instar Features of the Head in Caterpillars from Genus Peridea (Lepidoptera, Notodontidae)
Pattern and colouration of caterpillar head of all larval instar of 7 species from genus Peridea Stephens, 1828 are studied. Formation of caterpillar head pattern in ontogenesis is discussed. Diagnostic characters, both specific and larval instars, are recorded for the first time. Key to species according to larval instars is given. Evidently, only larvae of the 1st instar demonstrate different directions in the pattern formation. This characteristic can be used for clearing of taxonomic relations in the genera and on the earliest ontogenetic stages (1st larval instar) only. In the following (2nd-5th) instars, the pattern became more or less of the same type. It depends on stripes shape or colouration only and can serve as good specific diagnostic character. To determine larval instar, both width of the head capsule and head pattern should be taken into account.
The Chorionic Sculpture of the Eggs of Some Noctuinae (Lepidoptera, Noctuidae) from Ukraine
Descriptions and scanning electron microphotographs of the eggs of 10 species from 7 genera of the subfamily Noctuinae occurring in Ukraine are provided. The diagnostic characters of the genera and species are selected.
A key for identification of 39 species from 20 genera of Ukrainian notodontid moths based on the the eggs is provided. Reliable diagnostic characters, which do not disappear with the injury of eggs or eggs preserved for a long time in alcohol were used. The characters as egg shape, egg and chorion colour, shape of gnawed holes in eggs before setting out of caterpillars, the type of oviposition and the chorionic sculpture are applied. Clear characters that are typical for the live eggs, which vary in the process of egg development are revealed. These are characters of egg colour and pattern. In the key such characters are kept by stable signs that do not disappear aft er eggs traumatizing. The key is illustrated in details with photographs made using a digital camera and scanning electron microscope.
The eggs of 10 species Noctuidae from 6 subfamilies (Acronictinae, Metoponiinae, Cuculliinae, Heliothinae, Condicinae and Bryophilinae) occurring in Ukraine are examined, described, and illustrated with SEM. Th e diagnostic characters of examined species are carried out
The eggs of one species from family Nolidae (subfamily Chloephorinae) and seven species from family Erebidae (subfamilies Hermeniinae, Hypeninae, Phytometrinae and Catocalinae) occurring in Ukraine are examined, described, and illustrated with SEM. The diagnostic characters of examined species are proposed.
Larval cranial setae of each larval instar of 66 species belonging to 35 genera of Palaeartic Notodontid moths from Ukraine and Far East of Russia (Primorskii krai) was examined with the use of a scanning electron microscope. A comparison with outgroup species - Lasiocampoidea (Lasiocampidae), Sphingoidea (Sphingidae) and Noctuoidea (Erebidae: Lymantriinae, Arctiinae; Noctuidae) is conducted. Main kinds of setae during larval development and their transformation are discussed. Possible apomorphic and plesiomorphic states of the different characters are discussed in relation to the different taxa.
The eggs of 9 species Noctuidae belonging in 4 subfamilies (Plusiinae, Eustrotinae, Acontiinae and Pantheinae) are examined, described, and illustrated with SEM. The diagnostic characters of the eggs of examined species are given.
