Male vs Female Praying Mantis: Size, Behavior & Cannibalism Differences
Male praying mantis: smaller, 2–3 cm, flies well. Female: bulkier, 6–7 cm, shorter wings. Both hunt insects, but only females routinely devour partners during or after mating.
People assume “praying mantis” is a single species and picture a green ninja; when males vanish post-date, they blame misidentification. Knowing sex differences keeps classroom terrariums, nature photos, and horror stories accurate.
Key Differences
Size: females up to 3× heavier. Wings: males fly to find mates; females glide short distances. Behavior: males approach cautiously; females strike for extra egg nutrition, not aggression.
Which One Should You Choose?
Pick males for flight demos or safer handling. Choose females for dramatic predator footage—just isolate them before mating to avoid a one-snack romance.
Do males ever survive mating?
Yes, about 30% escape if the female isn’t hungry or if the male times his getaway perfectly.
Can you sex a nymph?
After the third molt, count abdominal segments: males have eight, females six—easy with a hand lens.
