Sphinx crassistriga
Sphinx crassistriga is a butterfly (moth ) from the family of moth ( Sphingidae ).
Features
The moths have thickened distal probe, carrying a large brown stain over most of the dorsal surface. The top of the body is pale - brown, with the faintest range is on the sides. From the sensor base to the collar extends on each side of an oblique black line. The edge of the collar and particularly the upper edge of the Tegula on mesothorax are broad black. The abdomen bears on the top center a black line and also on the sides of black spots. The proboscis is short and weak. The palps are slender hairy and rough. My first segment is pale. The rails ( tibiae ) of the front and middle legs wearing only a few apical spurs. The paronychium bears no praise.
The top of the front wings is brown with brownish- black spots: Two very oblique ante median Costallinien thwart the apex of the Diskalzelle. At it borders a short wiper on the Diskalzelle and a black mop consists of the wing vein CuA2 to the wing inner edge away, he meets approximately five millimeters in front of the base and to which he continues. The space between the wiping darkens posteriorly. Two strong discal Wipe located after the veins M3 and cua1; the front is longer at the Nominatunterart, however, less pronounced than in the subspecies Sphinx crassistriga aino. A third wiper extends from vein M1 to M2 and runs oblique. The Diskallinien, which are crossed by these Brushes are not flashy and designed as a black - brown spots that are clearly beyond the core CuA2. Apical is a strong oblique wiping and some Submarginalflecken. The edge of wing is brownish - black with white spots.
The bottom of both pairs of wings greyish - brown. The underside of the forewing bears a weakly developed Diskalbinde that runs closer to the outer edge than at the Diskalzelle. In addition, a fine Apikallinie is formed. The hind wings are brown on the top, where they are basally paler. The edge of wing is white spotted. The underside of the hind wings carrying two weakly developed distal binding.
The subspecies Sphinx crassistriga aino is smaller than the Nominatunterart and has bluish- gray dusted forewing tops. In addition, the two black Brushes are seen more clearly narrower, but after the veins M3 and cua1.
The caterpillars look at the last stage of the green color form of the pine hawkmoth ( Sphinx pinastri ) are similar, but are built stronger. In addition, they lack the fine, dark, broad segments of the lines. The caterpillars are apple green on the sides and wear yellow dots. A broken white line runs purely on either side of the middle of the back from the head to the last segment. Ventrolateral each run similar longitudinal lines. A broader reddish- brown line runs as from the head to the last segment. This line is limited on both sides by a broken, pure white bandage. The Analhorn is dark reddish- brown and granulated. It is set in a dark Dorsallinie. The head is oval and has two vertical medium brown cheeks and two dark brown hard on the face. The Nachschieber and Analklappen are reddish - brown. The spiracles are colored dark and orange.
Occurrence
The Nominatunterart is endemic in the mountainous areas of Honshu, Shikoku and Kyushu in Japan. Sphinx crassistriga aino is endemic to Hokkaido.
Way of life
The Nominatunterart is from mid- May to end of August ( Honshu ), detected early June to August ( Shikoku ) and mid-August ( Kyushu ). Although most moths were caught between mid-July and mid-August, save individual catches of mid-May to late June, a second generation in close. The second subspecies usually already flying in a generation focusing from late June until mid / end of July, with single finds, however, from April.
The caterpillars feed on pines ( Pinus ), but there is also evidence of larch ( Larix) and fir (Abies ).
