Thetidia plusiaria is a butterfly ( moth ) fromthe Spanner family (Geometridae).
features
butterfly
The wingspan of the males is 22 to 27 millimeters, that of the females 24 to 29 millimeters. Second generation butterflies are much smaller and usually only reach a wingspan of 20 millimeters. The upper side of the forewing is colored bright green. Orange colored specimens appear very rarely. Characteristic are two strongly jagged white transverse lines on the forewings as well as a distinctive white discoid spot , which is green in the center. A short, white longitudinal stripe can be seen below the discoidal spot. There are white wedge marks on the hem. The fringes are alternately green and white piebald. A small greenish central spot stands out on the white hind wings. The antennae of the males are combed on both sides, those of the females are weakly toothed.
Similar species
In Thetidia correspondens the green center in the discoidal spot of the forewings is missing and the fringes are not piebald. Likewise, the center on the hind wings is missing. Since this species occurs locally in Russia and some areas of Central Asia, there is no geographical overlap between the two species.
Distribution and occurrence
Thetidia plusiaria occurs in the middle and east of Spain , in the Pyrenees , on Mallorca as well as in Algeria and Morocco . In the mountains it rises up to 2400 meters. It inhabits mostly dry, open or bushy mountain slopes.
Way of life
The moths fly in two generations in June, July and September. A third generation sometimes appears in climatically favorable areas. They are nocturnal and fly to artificial light sources , but 80% of the males. The caterpillars were found on santolina ( santolina ), yarrow ( Achillea ) and mugwort species ( Artemisia ). Little is known about their way of life at the moment.
