Macrolophus pygmaeus is a species of bug from the family of soft bugs (Miridae).
features
The bugs are 3.1 to 3.9 millimeters long. The species of the genus Macrolophus can be recognized by the dark lines between the rather small compound eyes and the pronotum . The species looks very similar to Macrolophus rubi , but differs in the third segment of the antennae , which is only about 1.75 times as long as the fourth, instead of about twice as long as the similar species. The clavus is completely green and has never a dark tip, the antennae are a bit shorter and the body length of the adults is generally a bit shorter than that of the similar species, although there are overlaps here.
Occurrence and habitat
The species is distributed throughout Europe excluding the far north, south to North Africa and east across Asia Minor to Central Asia. It is widespread and not uncommon in Germany. Humid and shady as well as sunny, open habitats are colonized.
Way of life
The bugs feed on zoophytophagus. They live in Central Europe on forest ziest ( Stachys sylvatica ), rarely also on other mint family (Lamiaceae) such as sticky sage ( Salvia glutinosa ). The literature also mentions possibly questionable evidence of lung herbs ( Pulmonaria ), thistle ( Cirsium ) and ring thistles ( Carduus ). They also suckle on the glandular spherical thistle ( Echinops sphaerocephalus ), which is not native to Central Europe but is planted in gardens . The bugs first suckle on the leaves, later mainly on the flower heads of the host plants. The overwintering takes place as an egg. The nymphs hatch early in the year, so that the adults appear in April and May. The second generation nymphs can be seen in June, the adults in July and August, and in September at the most. The generations partially overlap, so that between April and August both nymphs and adults can be found.
