Pyrrhalta Fuscipennis
''Pyrrhalta'' is a genus of beetles in the leaf beetle family, Chrysomelidae. Species are distributed throughout much of the world, including much of the Northern Hemisphere and the Australian region.Nie, R. E., et al. (2013)Notes on black elytron species of ''Pyrrhalta'' Joannis and the description of a new species from China (Coleoptera, Chrysomelidae, Galerucinae).''ZooKeys'' 289 41-56. The taxonomy of the genus is not clear. Species are separated from those of other genera by the sometimes inconsistent comparison of questionable characters, such as the distribution of minute hairs. There is also little agreement on how to divide the group into subgenera. Former subgenera such as ''Xanthogaleruca'' are treated as separate genera by some authors, but not accepted as such by others. A definition of the genus used by some authors includes characters such as a hairy pronotum and elytra, gena (the spaces below the eyes) longer than the eyes themselves, and a labrum with a li ...

Pyrrhalta Viburni
''Pyrrhalta viburni'' is a species of leaf beetle native to Europe and Asia, commonly known as the viburnum leaf beetle. It was first detected in North America in 1947 in Ontario, Canada. However, specimens had been collected in Annapolis Royal, Nova Scotia in 1924. In 1996 it was discovered in a park in New York, where native plantings of arrowwood ('' Viburnum dentatum'' complex) were found to be heavily damaged by larval feeding. The UK-based Royal Horticultural Society stated that its members reported ''Pyrrhalta viburni'' as the "number one pest species" in 2010. The spined soldier bug, ''Podisus maculiventris'' is used and developed as a biological control agent against the beetle. Life cycle Viburnum leaf beetles go through one new generation of offspring per year. Eggs are laid throughout the summer and into October. Female beetles burrow into the underside viburnum terminal twigs and create 'spaces' in pith tissue. Then they lay eggs in clusters of 5-6 and cover them ...

Viburnum
''Viburnum'' is a genus of about 150–175 species of flowering plants in the moschatel family Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the honeysuckle family Caprifoliaceae. The member species are evergreen or deciduous shrubs or (in a few cases) small trees native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America and southeast Asia. In Africa, the genus is confined to the Atlas Mountains. Name The generic name ''Viburnum'' originated in Latin, where it referred to '' V. lantana''. Description The leaves are opposite, simple, and entire, toothed or lobed; cool temperate species are deciduous, while most of the warm temperate species are evergreen. Some species are densely hairy on the shoots and leaves, with star-shaped hairs. The flowers are produced in corymbs 5–15 cm across, each flower white to cream or pink, small, 3–5 mm ...
