Leptopteromyia mexicanae Martin, 1971 New Island Record. This small leptogastrine asilid that mimics wasps was originally reported from Maui (Howarth et al. 2012: 166) from a 2011 collection, but efforts to re-collect it from the island after the original record proved fruitless (M.T. Fukada, pers. comm. Jun 2013). recent collecting on O‘ahu, however, show that it has made it to this island. Given its small size, it may have been overlooked in general collecting and may be present on other islands as well. It is a predator on small soft-bodied invertebrates such as plant and leafhoppers and inhabits tall grassy areas where it perches on grass blades awaiting prey to ambush.
The Atherton Family Foundation, the Dana Anne Yee Foundation, and the City and County of Honolulu, Department of Parks and Recreation are thanked for providing funding to support the collecting efforts of WDP and DAY .
