Helenium S Virus
''Helenium'' is a genus of annuals and herbaceous perennial plants in the family Asteraceae, native to the Americas. They bear yellow or orange daisy-like composite flowers. A number of these species (particularly ''Helenium autumnale'') have the common name sneezeweed, based on the former use of their dried leaves in making snuff. It was inhaled to cause sneezing that would supposedly rid the body of evil spirits. Larger species may grow up to tall. The genus is named for Helen of Troy, daughter of Zeus and Leda. ''Helenium'' species are used as food plants by the larvae of some Lepidoptera species including ''Phymatopus behrensii''. Genus level properties: most conspicuously globe-like disk-shaped flowers, rays three-lobed at tip. Species Cultivation Numerous cultivars have been developed for garden use - mainly from ''H. autumnale'' and ''H. bigelovii''. They are useful for late summer and fall bloom, usually in less formal compositions. They are appropriate for nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phymatopus
''Phymatopus'' (originally: ''Noctua'' Linnaeus, 1758) is a genus of moths of the family Hepialidae (commonly referred to as swift moths or ghost moths), which consists of around 500 species and 30 genera. The genus was erected by Hans Daniel Johan Wallengren in 1869. They can be found across Eurasia and North America. Species can be distinguished by the different morphology of male genitalia and different forewing patterns, which vary in stripe colour and size and arrangement of spots. The stripes themselves consist of spots separated by dark veins which are fringed by thin black lines from both inner and outer sides.
