Lygaeus turcicus is a bug from the family of ground bugs (Lygaeidae).
features
The bugs become 10–12 mm long. They are dark gray to black in color. Two orange stripes run across the front wings , forming an approximately X-shaped pattern. The clavus is orange in color and only has a black spot at the rear end. The orange head is black in the postocular area. A wide orange transverse band runs over the rear part of the pronotum, which has two black spots on the front edge and two black semicircular areas on the rear edge.
distribution and habitat
Lygaeus turcicus is common in North America. In Canada, the distribution area is in the eastern half. In the United States, they range from California to North Carolina and New England. The species is not represented in the southeast, on the Gulf Coast or in the northwest of the USA.
Way of life
The bugs mainly suckle on the achenes of the garden sun-eye ( Heliopsis helianthoides ), although they can also be grown in the laboratory on the seeds of other plant species. The garden sun-eye also serves as a host plant.
Similar species
The related species Lygaeus kalmii , also found in the United States, looks very similar to L. turcicus . The most important distinguishing feature is the orange colored clavus of L. turcicus , which is black in L. kalmii . In addition, the head of L. turcicus has a much larger proportion of orange. The nymphs of Lygaeus turcicus differ from those of L. kalmii in that the abdomen is uniformly red in color, while bright longitudinal stripes can be seen in the second species.
etymology
It used to be assumed that L. turcicus , like the similar type of bug, L. kalmii, uses silk plants ( Asclepias ) as host and fodder plants. It wasn't until the 1980s that it was noticed that this was not the case. The name False Milkweed Bug , which is commonly used in English, is derived from this fact .
