Zygaena erythrus (
Hubner, 1806)
|
Zygaena erythrus, common name sluggish burnet, is a species of moth in the family Zygaenidae.
This endangered species can be found only in France and Italy. [1] [3] It prefers dry and rocky areas with sparse vegetation and limestone substrate, but it is also present in heathlands, in nutrient-poor grasslands and in broad verges in oak forests with the host plant Eryngium species, from sea level to over 1,500 metres (4,900 ft). [1] [4]
Zygaena erythrus has a wingspan of 25–33 mm. [5] These quite large moths show enlarged and confluent red spots on the forewings, surrounded by black in the distal part. Females are little bigger than males, with a yellow golden dusting and less defined markings. The mature larva is rather dark greyish, with two series of dorsal black spots. [6]
This species is very similar to Zygaena purpuralis, but it has red scales in the axillary area of the forewings, up to a third of the length. [4]
Z. erythrus Hbn. (= saportae Boisd.; minos Boisd.) (4a). Larger; antenna longer, with thicker club. The red colour of forewing restncted to 3 streaks , the distal one being wedge-shaped ; moreover, only the basal third of the hindmargin of forewing is red. South France, Italy and Sicily. In ab. irpina Zickert, from the Riviera, the cuneiform spots are confluent. — As magna [Seitz, [1907] ] (4 a) a very large form from the Abruzzi is sold by Staudinger; the posterior cuneiform spot is strongly widened and distally straight-truncate.— Larva dull greenish yellow, witli heavy black dots subdorsally and yellow side-spots (Sapokta); in some districts not distinguishable from the larva of purpuralis. On Eryngium and Thyme (Rouast). Hibernating; pupation at end of May. Imago in June and July; frequently sitting on Thyme and Eryngium. [7]
The life cycle involves only one generation per year. [6] Adults are on wing from the end of June to the beginning or mid August. [8] The hatching occurs between June and July. [6] The larvae feed on Eryngium species, [9] including Eryngium campestre [1] and Eryngium maritimum. [2] Full-grown larvae can be found from June. Pupation occurs within a cocoon usually adherent to the lower surface of the leaves, [6] but also on the ground between lichens, moss and parts of plants. [8]
