Features
The moths have a wingspan of 31bis 36 mm (33 to 38 mm ). The ground color of the forewings is fawn-colored, reddish-brown or yellow-brown. Especially the dark brown copies can also be tinted gray. The wide, usually more or less distinctly white -fringed midfield is significantly darker than the ground color, usually light brown, brown, dark brown to gray-brown, depending on the base color. It is often centrally brightened somewhat. In the same color as the middle and the white fringed outwardly root or Basalfeld is held. The Saumfeld will gradually toward the dark Saumrand. It may have a " lively " purple sheen. The shaft line is designed as a bright jagged line. The hem line is also mostly bright and stands out clearly in darker specimens from. The moths vary relatively little in the drawing and a little stronger in color. The Flügelapex of the front wing is pointed, often remains a distinct dark Apikalstrich available.
The hind wings are pale gray-brown and darker towards the hem. There is also a bright jagged line in Saumfeld available as well as a weakly developed centerline. The hemline is also bright
Egg, caterpillar and chrysalis
The pale yellow egg is spherical, the surface is smooth.
The caterpillar is green, whitish on the ventral side, with whitish warts and black point, white edged spiracles. She is brown bristles with clearly distinct, yellowish segment incisions. Occasionally, a pink colored dorsal line is formed. The other longitudinal lines are barely hinted at.
The red-brown doll is dull, the cremaster has two pointed, longer bristles and several fine, curved bristles.
Similar Species
The species is easily confused with the Brown -banded wave welts tensioner ( Scotopteryx chenopodiata ). When mallow root and the blade tensioner midfield is surrounded by white boundary lines. The root field is in the former kind usually colored differently from the midfield.
Geographical distribution and habitat
The species is distributed from North Africa, the Iberian Peninsula and the British Isles in the west, across Southern, Central and Eastern Europe until well after Siberia ( Altai Mountains ) into it. In the north of the area dates back to the middle Fennoscandia, in the south of the western Mediterranean islands, over Italy, the Balkans, Asia Minor, the Caucasus to the Tajikistan. But they always happens only very locally and is almost always rare. The species prefers extensively Cultivate meadows, roadsides, field edges and roadsides, and gardens, school gardens, herb gardens and Waste places, etc., wherever mallow, the food plants of the caterpillars grow. In the Alps, it rises to 1200 m above sea level at
Way of life
The Mallow blade tensioner is a generation in years; the moths fly from August to November. They are nocturnal and come to light. During the day they hide in vegetation and are difficult to flush. The egg overwinters. The caterpillars are rarely held between April and June, and July. They live on and feed on the leaves of mallows, namely are: Rose Mallow ( Malva alcea ), Musk Mallow ( Malva moschata), way - mallow ( Malva neglecta ), Marshmallow ( Althaea officinalis ) Marshmallow Hanfblättriger ( Althaea cannabina) and shrub poplars ( Lavatera sp.). In this case, the sheet material is eaten down to the midrib. During the day, the caterpillar rests on the underside of leaves. If the caterpillar is disturbed, it can be incurved fall to the ground. Curled she looks like a Malvensamen. Pupation takes place in a cocoon on the ground in July or August.
Systematics and Taxonomy
The species was described in 1809 by Adrian Hardy Haworth as Geometra Clavaria first time scientifically. The type appears in the older literature as Larentia cervinata ( Denis & Schiffer Müller, 1775) (eg). Geometra cervinata Denis & Schiffer Müller, 1775 is an unjustified emendation and also a misidentification of Phalaena cervinalis Scopoli, 1763rd
