Features
The moths reach a forewing length 12.5 to 15.5 mm in males and 8.0 to 11.0 mm in females. Head, thorax, legs and abdomen shining green, gold green or bluish green. The forehead is about 1.5 times as wide as the compound eyes. The antennae are short and bluish shimmer. They have a slender stem and consist of 31 to 35 segments. The sensors are comb-shaped. The wings are translucent and scantily provided with narrow scales. The front upper wing surface shimmers green, gold green or bluish green. The rear upper wing and the wing undersides are light gray.
In the male genitalia the uncus is short and the Vinculum narrow. The dorsal Valven are longer, the ventral part is distally provided with a square projection. The aedeagus is small and narrow, slightly curved and bears two nearly straight, slender Cornuti. The 8th sternite covers the entire segment and extends beyond the rear edge.
In the female genitalia the ostium is narrow and rounded. The proximal part of the ductus bursae is broad and long. He is well sclerotized, the proximal portion has a smooth surface and a short grooved translucent area. The distal portion of the ductus bursae is straight and nearly as wide as the corpus bursae. In some specimens the ductus bursae - - extension may be missing, however, is at the point where the extension attaches else, nor a sclerotized spot visible.
The egg is pale yellow.
Head and legs of the caterpillar are black that is also black Prothorakalsegment there are white lines back side. The body is marked with yellowish brown and reddish purple back and side lines. The warts are reddish brown, the belly is yellow. The crawler body is provided with one or more tiny spiny tubercles observed with the naked eye appear as black dots.
The pupa is light brown and shiny. The cocoon is very thin and white.
Similar Species
In the distribution area, there are several species with broad wings and pointed probes, similar to J. budensis:
- Central Spain and southern France: J. budensis occurs together with Jordanita subsolana, Jordanita hispanica, Jordanita globulariae, Jordanita vartianae and Jordanita notata.
- Eastern Europe: J. budensis occurs here along with Jordanita subsolana, Jordanita globulariae and Jordanita notata.
- Southern Russia, the Caucasus and Transcaucasia: Jordanita budensis occurs together with Jordanita subsolana, Jordanita notata, Jordanita paupera and Jordanita volgensis. The distinction between the last two types is only possible through a genital examination.
- Turkey: J. budensis comes (only in southern Turkey ) and Jordanita kurdica (in eastern Turkey ) before along with Jordanita subsolana, Jordanita globulariae, Jordanita notata, Jordanita paupera, Jordanita volgensis, Jordanita hector. A reliable differentiation of species is possible only through a genital examination.
J. budensis flies very early in the year, but usually has a month earlier than the similar species. It has less than 36 segments, the shortest probe and has very translucent wings.
Jordanita subsolana is beschuppt denser and darker, the shine on the body and the front upper wing surface is weak and mostly absent. In the males, the 8th Abdominalsternit covered the whole segment, but it does not project beyond the rear edge. In the females the 7th Abdominalsternit similar to budensis of J..
Jordanita globulariae and Jordanita vartianae are densely scaly and the body and the front wing tops have a strong green or greenish tinge. The 8th Abdominalsternit covers only the back half of the segment, so that the light over the rear edge also reaching ventral appendages of the blades are visible. In females, the asymmetric ostium is clearly visible.
In Jordanita hispanica the front wing tops shimmer characteristic yellowish green, the Fühlerkämmung is significantly shorter. Although the eighth Abdominalsternit covers the whole segment, but not enough on the rear edge. In the females the 7th sternite similar to budensis of Jordanita.
Jordanita notata has slightly narrower wings, the meshing of the sensor is very short. In the males, the narrow 7 Abdominalsternit extends to the rear end of the segment.
Dissemination
Jordanita budensis has a disjoint distribution area with isolated populations. The species occurs in central Spain, southern France, Italy, in the east of Austria and Hungary, on the Balkan Peninsula, Greece, Ukraine, including the Crimean peninsula, in the European part of southern Russia, the Caucasus and Transcaucasia, Turkey, to the south Siberia, in Mongolia and the Amur region. Are populated steppe habitats in the plains and in the mountains. To the west of the Alpine height the nature rises up to 2400 meters.
Biology
The females lay eggs singly or in short rows around noon on the food plants from. In Western Europe, the caterpillars develop on the rispigen knapweed (Centaurea paniculata) in Central Europe felt knapweed (Centaurea triumfettii ) and on the Crimean peninsula to Feinblättriger Yarrow ( Achillea setacea ). The caterpillars pupate in the soil under the host plant in a thin cocoon. The moths emerge early in the morning and fly during the hottest time of day. Flight time varies depending on the altitude, it begins in the lowlands in late March and extends in mountainous regions by July.
