Sphinx Crassistriga is a butterfly ( moth ) from the family of moth (Sphingidae).
features
The moths have distally thickened antennae that carry a large brown spot over most of the dorsal side. The top of the body is pale brown with the palest area on the sides. A sloping black line runs from the antenna base to the collar on each side. The edge of the collar and especially the upper edge of the tegula on the mesothorax are broadly black in color. The abdomen has a black line in the middle on the top and black spots on the sides. The proboscis is short and weak. The palps are slender and coarsely haired. Your first segment is pale. The splints ( tibia ) of the front and middle legs have only a few spurs apically. The paronychium carries no praise.
The upper side of the forewings is brown with brownish-black spots: two very oblique antemedian costal lines cross the apex of the disc cell . To them a quick wipe borders on the Diskalzelle and a black mop is made from the wing vein path CUa2 the wing inside edge on, he meets about 5 millimeters in front of the base and continues to he. The space between the wipes darkens posteriorly. There are two strong discal wipes after the leads M3 and CuA1; the anterior is longer in the nominate subspecies, but less pronounced than in the subspecies Sphinx crassistriga aino . A third swipe extends from wire M1 to M2 and runs more diagonally. The disc lines that are crossed by these wipes are not noticeable and are designed as black-brown spots that become more evident beyond the CuA2 vein. Apically there is a strong oblique wipe and a few submarginal spots. The wing edge is brownish-black with white spots.
The underside of both pairs of wings is grayish-brown. The underside of the forewings has a weak discal band, which runs closer to the outer edge than to the discal cell. In addition, a fine apical line is formed. The hind wings are brown on top, but are paler at the base. The wing edge is spotted white. The underside of the hind wings has two weakly formed distal bands.
The subspecies Sphinx crassistriga aino is smaller than the nominate subspecies and has bluish-gray pollinated forewing tops. In addition, the two black wipes after the wires M3 and CuA1 are narrower but more clearly visible.
In the last stage, the caterpillars look similar to the green color of the pine hawk ( Sphinx pinastri ), but are more strongly built. They also lack the fine, dark lines that encompass the segments. The caterpillars are apple green on the sides and have yellow spots. A broken pure white line runs down the middle of the back from the head to the last segment. Similar longitudinal lines run ventrolaterally. A wider reddish-brown line also runs from the head to the last segment. This line is bounded on both sides by an interrupted, pure white band. The anal horn is dark reddish-brown and granulated. It is located in the middle of a dark dorsal line. The head is oval and has two vertical medium brown cheeks and two dark brown stripes on the face. The slider and the anal valves are reddish-brown. The stigmas are dark orange in color.
Occurrence
The Nominatunterart is in the mountainous regions of Honshu , Shikoku and Kyushu in Japan endemic . Sphinx crassistriga aino is endemic to Hokkaidō .
Way of life
The nominate subspecies has been recorded from mid-May to late August (Honshū), early June to August (Shikoku) and mid-August (Kyūshū). Even if most of the moths were caught between mid-July and mid-August, individual catches between mid-May and late June suggest a second generation per year. The second subspecies usually flies in a generation with a focus from late June to mid / late July, but with individual finds from April.
The caterpillars feed on pines ( Pinus ), but there is also evidence of larches ( Larix ) and firs ( Abies ).
