The attraction of two Chymomyza species, C. procnemoides and C. aldrichii, to the same damaged tree over 19 days in summer 1987 near Mt. Lake Hotel, Giles Co., Virginia is documented, confirming a previous report that Chymomyza species may be sympatric on the same fresh damaged tree/cut wood. A total of 17 males and 7 females were captured. An excess of males to females captured has been reported in Japan and Hungary.
