The jordanita globulariae ( jordanita globulariae ) is a butterfly from the family of burnet (Zygaenidae).
features
The moths reach a forewing length of 10.5 to 17.0 millimeters in the males and 7.7 to 10.1 millimeters in the females. The head, thorax , legs and abdomen shimmer green, bluish green or blue, although the shimmer on the abdomen is less intense. The sensors consist of 37 to 42 segments. The wings are broad, the upper surface of the forewings shimmers green, bluish green or blue. The hind wing is slightly translucent , the upper side is gray to light gray. The undersides of the wings are gray. The females are significantly smaller and have narrower and distally more rounded wings. The species is very variable in a large number of characteristics. These include size, color, intensity of shine, antenna length, wing veins and genital morphological features.
In the male, the valve processes ventral to the sacculus are very long. The aedeagus is about five times longer than it is wide. There is a group of fine needles on the bladder, a field with spines is missing. The 8th abdominal sternite covers only the proximal part of the segment so that the distal valve processes are visible after removal of the abdominal scales .
In females, the ostium is rounded and asymmetrical with respect to the abdomen axis. The antrum is translucent, wider than the ostium, and grooved. The bursal duct is short, translucent, kinked and slightly curved. The corpus bursae is egg-shaped, the characteristic needles are very small and fragile and only visible under the microscope. The 7th abdominal sternite is slightly indented distally , so that the asymmetrical ostium is clearly visible after the abdominal scales have been removed.
The egg is greenish yellow.
The color of the caterpillars is variable. The head and back of the prothoracic segment are brown. The body is gray, gray-brown or yellowish gray and drawn with dark gray lines. The warts are reddish, the legs are black-brown.
The pupa is pale brown or yellowish brown to greenish black.
The cocoon is greenish white or brownish gray and surrounded by an elongated, oval web of silk and earth particles.
Similar species
J. globulariae is so variable in color and size that it can be confused with almost all broad-winged species. In the females, the rounded, asymmetrical ostium is freely visible. J. globulariae can be distinguished from similar species by genital morphology.
distribution
The knapweed green ram is widespread in the west from the Iberian Peninsula across Western , Central and Eastern Europe to the Urals in the east. In the south, the distribution area extends across the Balkan Peninsula to northwestern Turkey . In Spain and in the south of France the species colonizes dry slopes or grassy, flower-rich clearings in forests, and occasionally also slightly damp meadows. In the rest of Europe, the species lives on moist meadows or dry grassy hills. In northern Italy the species is restricted to dry grasslands on the plains.
biology
The females lay the eggs in rows on the underside of the leaves, this happens during the warmest time of the day. The larvae develop in knapweed species ( Centaurea ), the tuberous thistle ( Cirsium tuberosum ) and globularia types ( Globularia ). The cocoon is placed close to the surface of the soil or in the leaf litter.
