BARB, WHAT KIND OF SEX SMELL DO THEY LEAVE? My man say's they have a smell also but i have never smelled it!! nOW I KNOW STATE'S HAVE DIFFERENT BUG'S. Also cricket's are black.Tho have seen brownish one's as well. But then thought God made some bird's different color's. So maybe some bug's are different in color as well. The only one ii ever think of is the Mallard Duck. The male is beautiful where the hen is tannish brown. But i know the Asian Lady bugg's do not sleep all winter like flies. Today a big male fly came awake in the living room ceiling light and came out and flew around a few minute's then must have realised he was awake to early and went back into the light and has not come out again that i aw. Viola.
