Story summary
- Anastatus japonicus shows a left-side approach bias, unlike right-biased Trichogramma spp.
- The bias suggests a family-specific adaptation that warrants further comparative research.
- Lateralized behaviors are crucial in mass rearing, and disruptions lower mating success by 15-25%.
- Males court with antennal tapping, stimulating female receptivity and mating success.
- Females mated with non-virgin males produce fewer daughters, and virgin males matter.
