Taxonomy

Family: Tenthredinidae
Family common name: common sawflies
Subfamily: Blennocampinae
Tribe: Blennocampini
Genus: Apareophora Sato, 1928
Subgenera: none

Background

The Tenthredinidae are the most species-rich family and are found throughout the world, in all continents but Antarctica. They are known as the “common sawflies.” They can generally be recognized by a cylindrical body and long, segmented antennae. Otherwise, they come in a variety of colors, sizes, and forms (Goulet 1992).

Sawflies in the subfamily Blennocampinae have a diverse set of life histories and habits. Many species are restricted to subtropical and tropical regions, but the genus is still fairly species-rich in North America. Blennocampinae includes many sawflies that feed on ornamental and forestry crops. This subfamily can be recognized by wing venation and bidentate mandibles (Smith 1969d).

Apareophora is medium-sized, about 6.5 mm in length and entirely black, with light-colored striping on the legs and hyaline wings (Smith 1969d).

Diversity

There are 9 described extant species worldwide. Two species occur in North America (Taeger et al. 2018).

A key to North American species is included in Smith 1969d.

Genus characters

May be confused with

Apareophora can be confused with similar species in the subfamily Blennocampinae. It can be distinguished from most other genera by the simple tarsal claw, absence of hind wing cell M, and a narrow malar space (Smith 1969d).

Exotic pest species of concern

Apareophora forsythiae, also known as the forsythia sawfly, is a minor pest in South Korea (Park and Lee 1993).

Host associations

In North America, Apareophora feeds on Spirea (meadowsweet), including Spirea salicifolia (willowleaf meadowsweet) (Smith 1969d, Goulet 1992).

Life history

unknown

Distribution

World: This genus is known from North America and in East Asia: Korea, China, and Japan (Taeger et al. 2018).

North America: Apareophora occurs in southeastern Canada and the northeastern United States west through the Great Lakes region (Smith 1969d).
