From: Oviposition traits generate extrinsic postzygotic isolation between two pine sawfly species
BCL females with pinetum-like oviposition traits have higher oviposition success on P. strobus. a Oviposition success (proportion of females with at least one hatching egg) was higher for BCL females that had a pinetum-like oviposition pattern (<3 eggs per needle) compared to females that lacked this pattern (>3 eggs per needle) (P <0.05). b Females that laid successfully had shorter ovipositors than those that did not (P < 0.05)
