Here we describe tandem oviposition (contact guarding) in Lestes congener and the use of dry stems of the sedge Eleocharis obtusa as oviposition substrates at a pond in New York State. Pairs formed away from the pond, then flew to Eleocharis patches on dry land 0.5–3 m from the water’s edge. Some copulations occurred at…
The hatching phenology of 15 Odonata species was studied under seminatural conditions to find out how the hatching modes of typical species of summer dry temporary waters (vernal ponds) differ from those of species inhabiting both permanent and temporary waters. We attempt to answer the following questions. (1) Do vernal pond species hatch earlier in…
Of the many Zygopteran genera that occur in the Neotropics, only five (Hetaerina, Archilestes, Lestes, Argia, and Ischnura) are represented north of 40°N in North America, and only three of these (Hetaerina, Archilestes, and Argia) probably had a tropical origin. In the two genera of Lestidae (Archilestes and Lestes) the life history of temperate-zone populations…
