Explanation of Names
Tiphia vernalis Rohwer, 1924
The male is distinguished from other eastern species by having an impunctate and polished stripe along the middle of sternite 6. This stripe widens at the posterior and has white setae along the sides. The female is distinguished by having 2-3 short and indistinct longitudinal grooves on the middle of the pronotum.(1)
native to e. Asia, adventive in NA, established in ne. US (NH south to NC, west to MI, OH, KY, & TN)(1)
May - early June
Used as a control measure against the introduced Popillia japonica (Japanese beetle). Adults feed on honeydew.(1)
Introduced from Korea and China in 1925 to combat the Japanese beetle (Popillia japonica). A related species, T. popilliavora was introduced from Japan in New Jersey in 1921-22 for the same purpose. They are both very slow to disperse, therefore, later on some were distributed to other parts of the country. (Mahr, 1999)
