Suction blacklight trappings have been conducted at Bet Dagan since 1978. Tabanus arenivagus has been caught only during 1992-94. Seventy-one specimens, all females, were caught by these traps, demonstrating that females are attracted to the wavelength range of 340-380 nm radiated by the mercury-vapor lamps of these traps. This constitutes a new finding among the Tabanidae species of the Mediterranean region.
