Vitacea admiranda (Hy. Edwards, 1882)
Sciapteron admirandus Hy. Edwards, 1882
Tirista argentifrons of authors not Walker, 
* phylogenetic sequence #640067
Explanation of Names
Admiranda is derived from Latin for "admirable/astonishing."
Some (all?) records of Tirista argentifrons north of Mexico appear to be Vitacea admiranda. The type locality for T. argentifrons is southern Mexico. There are separate BINs at BOLD for these two species. They are each others closest neighbors and form a branch separate from the branch containing other species in the genus Vitacea, suggesting the possibility that admiranda might belong in the genus Tirista. Coloration of abdominal segments and a lack of pencil tufts may not separate these two species.
Wingspan: ♂ 25-30 mm, ♀ 34 mm. (1)
Forewing length: ♂ 9.5-15 mm (Bordelon & Knudson, 1998).
Adult - resembles Polistes paper wasps.
Throughout Texas south into Mexico.
Adults active June though November in late afternoon and early evening (Bordelon & Knudson, 1998).
Larval hosts are likely grapes (Vitaceae). Knudson & Bordelon observed the adults in association with mustang grape
This species was practically unknown before synthetic pheromones, only three specimens in major collections for the first 100 years. It is now known throughout Texas, and is exquisitely sensitive to pheromone residues on skin or clothing. (2)
Males attracted to 1:1 ratio of Z,Z,ODDA and E,Z,2,13,ODDA pheromones, but some males flew directly to the Z,Z,ODDA lure (Bordelon & Knudson, 1998).
