The mourning tensioner ( Baptria tibial ) is a butterfly ( moth ) from the family of the tensioner (Geometridae).

features

The moths reach a wingspan of 22 to 26 millimeters and have black fore and hind wings. From the center of the front edge of the forewings, a wide, white band extends towards the inner corner, but does not reach the latter. Specimens with a white band on the hind wings were described as forma tetraleucotaenia Zukowsky. The egg is light green to white, slightly oval and slightly flattened. The caterpillar is slightly narrow at the front, overall slightly flat, without significant side folds and with yellowish segment incisions. The back line is broad, brown-red or purple-brown and partially dissolved in heart-shaped spots. The doll is stocky and brown in color.

distribution

The mourning wrench occurs very locally and rarely in damp places in light deciduous forests, preferably in stream valleys, also on calcareous forest slopes up to 1,200 meters above sea level in the foothills of the Alps, in northern Germany it has not been permanently detected, previously sporadically in Thuringia, but threatened with extinction there, however occurring in Scandinavia, Finland and Poland.

Way of life

The moths fly during the day, mainly when the sun is shining in the morning hours in clear forest areas or at the edges of the forest rich in bushes. The moth is extremely shy. When sitting, the wings are constantly moved up and down. In the event of a disturbance, the moths often drop and pretend to be dead. However, in the event of danger they immediately fly up. The females lay the eggs on the leaf tips of the forage plant in the afternoon. The caterpillar feeds exclusively on Spiked St. John's wort ( Actaea spicata ). The caterpillar is also very shy and immediately leaps away from the forage plant in case of danger. Pupation takes place on the ground under leaves and moss. The pupa hibernates, often several times.

Flight and caterpillar times

The mourning wreath flies in one generation in June / July. The caterpillars live in July and August.

Hazard and protection

The species is considered endangered and is classified in category 2 of the Red List of Threatened Species in Germany, and in Bavaria as "extremely rare with geographical restrictions."
