SF Coreoidea: Coreoidea Species File (version 5.0, Jun 2018). Probably the warm and dry summer contributed to their rapid reproduction and propagation. In warmer areas, the species also occasionally appears as a pest in pistachio and citrus plantations.Ģ018 I found Leptoglossus occidentalis for the first time in Chemnitz (surprisingly 5 specimens on different days and places in the urban area). The adults of Leptoglossus occidentalis are good flyers, which are often found in the settlement area in search of suitable wintering places.īy sucking the bugs can reduce the yield and quality of coniferous seeds. They feed mainly on the seeds of their host plants. Imagines of this species were found in Rhineland-Palatinate from July to November. They go through 5 larval stages until they moult to the imago. Later they feed on the seeds in the cones. The young larvae suck on the needles, flowers and young cones. After about 10 - 14 days the larvae hatch. ![]() In the spring, after hibernation and mating, the females lay eggs in rows along needles of the host plants. Host plants of Leptoglossus occidentalis are conifers, preferably different species of pines ( Pinus) and Douglas firs ( Pseudotsuga menziesii), but also fir ( Abies), spruce ( Picea), cedar ( Cedrus) and juniper ( Juniperus). In warmer areas several generations can be passed through (in Southern Europe 2). The Western Conifer Seed Bug Leptoglossus occidentalis usually forms one generation per year in Germany. The tibiae of the hind legs are leaf-shaped widened. The lateral edges of the abdomen (connexivum) are brown and white spotted. We tested the hypothesis that the western conifer seed bug, Leptoglossus occidentalis Heidemann, uses a substrate-borne vibratory signal for short-range. Mostly on conifers in forests, parks and gardens, often in settlement areas.ĭescription: Leptoglossus occidentalis is a 16 - 20 mm long, predominantly reddish brown bug with a fine white zigzag pattern in the middle of the wings. The species was first detected in Germany in 2006. First detected in northern Italy in 1999, it has spread rapidly since then. The Western Conifer Seed Bug, originally native to the west of North America, was introduced into Europe. Leptoglossus occidentalis Heidemann, 1910 Amerikanische Kiefernwanze Western Conifer-Seed BugĬlassification: Leptoglossus occidentalis belongs to the subfamily Coreinae, tribe Anisoscelini.
