Rhodostrophia
Broom - Rotrandspanner ( Rhodostrophia calabra )
The genus is a species-rich genus Rhodostrophia the butterfly family of the tensioner ( Geometridae ). A total of 76 species are expected to this genus. For Europe, eight species are given. In German-speaking only two species occur.
Features
It is rather small moth with a wingspan of about 20 millimeters to approximately 40 millimeters. In the wings is usually a double areole present. The core, which separates the two, is based on the cell. The veins R2 to R4 are stalked. The vein R5 extends from the apex of the second areola. On the hind wings the stem of Rs and M1 is relatively short. The veins M3 and cua1 are usually separated. The antennae of the male are quadripektinat. The proboscis is well developed, the palpi are short to medium in length.
In the male genitalia the uncus is usually very long and usually diagnostic of the Art The Gnathos is present, the shape of the blades is also often characteristic of the species. The aedeagus is elongate and relatively slim: it is slightly bent with characteristic features at the top. The sternum A8 is bilobed at the rear end. In the natural position of the two lobes are bent down.
In the female genital apparatus of the ovipositor has no ventral appendages. The ductus bursa is sklerotinisiert and extended at the rear end. In contrast, the corpus bursae is only surrounded by a membrane. The Signum is composed of paired, elongated sclerites with longitudinal ribs.
The eggs are usually longitudinally ribbed. The caterpillars are relatively very long and slender. The doll has a ausgelängten cremaster. It has four pairs of bristles, a pair of terminal, three pairs each marginal ..
Geographical distribution and habitat
The species of the genus Rhodostrophia come from Europe prior to Taiwan. Most species of the genus live in West and Central Asia. A few species occur in the temperate zones of the Palaearctic. The species live in dry and moist habitats. However, they are mostly heat -loving.
Phenology and life
The species of the genus are uni- up plurivoltin, depending on habitat. In many species, the beads are still unknown, and thus the crawler food plants. For species, of which the life cycle is fairly well known, are the most polyphagous caterpillars also various herbaceous plants, with some emphasis on a legume ( Fabaceae ) is observed. Where known, the caterpillar hibernates.
