Jordanita hispanica is a butterfly fromthe ram family (Zygaenidae).
features
Males have a forewing length of 9.1 to 14.2 millimeters. The females have narrower wings and are significantly smaller with a fore wing length of 6.4 to 9.0 millimeters. Specimens from Spain are larger than those from France. In the east of the Pyrenees there are large specimens with dark green shimmering forewing tops. These were called the subspecies J. h. danieli (Alberti, 1937). The head, thorax and abdomen shimmer light green or bluish green. The antennae are very slim and combed short, they consist of 36 to 38 segments. The upper side of the forewings shimmers yellowish green, golden green or bluish green. The upper side of the hind wing is light gray and slightly translucent . The undersides of the wings are light gray and have no shimmering scales.
In the male, the aedeagus has a distinctive, pointed cornutus. This has a wide rounded base with a slightly prickly surface and a very long and slender tooth-like distal section. The 8th abdominal sternite reaches the posterior edge of the segment.
In females, the ostium is wide. The pocket-like antrum is provided with a sclerotized ring proximally and translucent distally . It is smooth and laterally has a transparent U-shaped structure. The distal part of the ductus bursae is translucent, proximally wider and furrowed. It is slender, kinked and slightly twisted distally. The corpus bursae is egg-shaped and relatively wide at the point of attachment of the ductus bursae and ductus seminalis. The 8th sternite has a short, medial , posteriorly directed process.
The egg is yellowish green.
Only a description of the third stage (L 3 ) is available for the caterpillar . As a result, the head is blackish brown, the translucent breast segment is provided with an inverse, blackish brown T-shaped sclerotization. The body is light green and has almost no further drawing.
The remaining caterpillar stages, the pupa and the cocoon have not yet been described.
Similar species
In Spain and France J. hispanica occurs together with Jordanita budensis , Jordanita notata , Jordanita subsolana , Jordanita globulariae and Jordanita vartianae . The sympatric species have a similar habitus and pointed antennae.
Jordanita subsolana is larger and darker, the forewings hardly shimmer at all. The antennae are longer and have a longer comb in the males, in the females they are strongly serrated.
Jordanita globulariae and Jordanita vartianae can be easily distinguished from J. hispanica by brushing off the scaling of the last abdominal segment. In the case of J. hispanica, the 8th sternite in the males extends to the rear edge of the segment, in the similar species it covers only half of the segment. The asymmetrical ostium is clearly visible in the females.
Jordanita budensis also has short antennae, but the combs are longer in the males and the antennae are more serrate in the females. In the males, the last abdominal sternite extends beyond the posterior edge of the segment.
Jordanita notata is larger than J. hispanica , the antennae are slightly shorter, but the comb is equally short in both species. There are no external distinguishing features in the females, so that a reliable separation of the two species is only possible genitally morphologically.
distribution
Jordanita hispanica is common in Spain , Portugal, and southern France . The species inhabits rocky, dry grasslands on the plains or on slopes and steppe biotopes .
biology
The caterpillars live in southern France on the panicle knapweed ( Centaurea paniculata ). The moths fly in the late morning and mainly feed on the flowers of widow flowers - ( Knautia ), scabioses - ( Scabiosa ) and knapweed species ( Centaurea ). They rest during the hottest time of the day and resume flight activity in the late afternoon.
