Monalocoris filicis is a species of bug from the family of soft bugs (Miridae).
features
The bugs are 2.0 to 3.1 millimeters long. They have a golden brown base color and a pale orange head and are therefore easily recognizable. The adults are always fully winged (macropter). The species can only be confused with Bryocoris pteridis , from which it can be distinguished by the first antennae , which is shorter than the head is wide.
Occurrence and habitat
The species is distributed in Europe and Asia to Korea and Japan. In Germany and Austria it is widespread and usually common. In the Alps it rises to the tree line. Deciduous and coniferous forests and moist, open habitats such as bogs or the banks of streams are settled.
Way of life
The bugs live as well Bryocoris pteridis at various ferns of the family of polypodiaceae (Polypodiaceae), particularly on Genuine male fern ( Dryopteris filix-mas ), and the bracken ( Pteridium aquilinum , Family Dennstaedtiaceae ). Occasionally, the bugs appear together with Monalocoris parvulus . They primarily suckle the immature spore systems, and in late summer also the vegetative tissue of the plants. The males are avid fliers and swarm during the mating season, which means they can also be found on other plants. When disturbed, the animals occasionally drop from the plants to the ground, which is unusual for soft bugs. Unlike Bryocoris pteridis, the species overwinters as an imago in the dry remains of its host plants on the ground, in the litter or on branches of conifers such as spruces ( Picea ). The females lay their green eggs on the host plants from May to early June, where they can hardly be distinguished from the equally colored spores. Nymphs are mainly to be found in June and July, adult bugs from the end of June, during the mating season. In September / beginning of October the adults leave the host plants.
