The former is usually territorial latter uses sneaky mate securing tactics. When orange-winged males failed to establish territory, they became floaters that day. Hyaline-winged perched around their territories often, formed in tandem without any apparent courtship behavior when found females. Their copulation frequency was higher duration longer than those males. A few females oviposited remating. Total oviposition with a hyaline-winged male mated more 32 min per on average day Females copulated often remated residents before oviposition. bouts after mating short (15 min), while long (66 min). As result, total an about 40 reproductive success may be similar
