The insertion of the Odonata ovipositor in the plant tissue generates a scar that surrounds the eggs (trace). In insects, individual egg traces are known to vary in size, but their variation in individual shape is mostly unknown. Twenty-four specimens ...

1 Introduction Occasionally, plants serve as substrates for insect oviposition . In fossil leaves, endophytic oviposition is revealed by the presence of scars (traces) on the surface, which is generated in response to the lesion caused by the ovipositor [1-5]. Since the Palaeozoic, there is evidence of endophytic oviposition in fossil leaves ...
Different Oviposition Strategies of Closely Related Damselfly Species ...
Endophytic oviposition is an ancient strategy for egg laying in Odonatoptera; it is documented from the Triassic, but its origin may be even older [6, 7]. The endophytic ovipositor of damselflies consists of three pairs of valvulae to facilitate oviposition into substrates, such as plant tissues [8, 9].
To evaluate hypotheses about the evolutionary history of plant-insect interactions, it is essential to document the macroevolutionary dynamics of endophytic oviposition . We review endophytic oviposition and its association with host-plant taxonomic diversity (composition and richness), and how this close relationship may have changed over time.
Ecomorphology of insect ovipositors
The ovipositor is one of the key innovations that helped insects colonize the Earth. The functional specialization of the ovipositor and new egg-laying strategies allow insects to benefit from exploring new oviposition sites. In this chapter, following the introduction of general terminology, we broadly overview the basic ovipositor designs across insect orders, summarizing structural ...
Records of endophytic oviposition are relatively scarce, with previous earliest reports from the Middle to the early Late Triassic. Nevertheless, several Paleozoic insect taxa have been sus- pected of this reproductive behavior, but without any direct evidence. Specimens of Calamites cistii (Sphenophyta;
Key Details About Endophytic Oviposition And Ovipositor Position Variation
̌ les lack a well-developed ovipositor and release the eggs in the water or deposit them on the surface of periaquatic objects. The females ating, females with an endophytic behavior, some-times in tandem with the male, select a plant subst ate to place their eggs. For this, the female contacts the substrate with its ovi-positor , located at ...
The Evolution of Oviposition Strategies The diversity exhibited in phasmid ova and oviposition strategies is striking. Our results unequivocally demonstrate that the ancestral oviposition strategy for stick and leaf insects is to remain in the foliage and drop or flick eggs to the ground (Figures 4 - 6) as suggested previously (Bradler, 2009
