Marcia Jacobs confirmed that Sehirus cinctus cinctus females guarding their eggs use a twitching movement near the time of hatch that synchronizes the hatch process, resulting in enhanced offspring success.

Josh Rosero clarified that the improved offspring success that resulted from female manipulation of the eggs near hatch (twitch of mother’s legs while guarding eggs) also translated into improved success of adults.

Mona Munshi used SEM to determine that trophic eggs of Parastrachia japonensis have fewer micropyles (structure that allows sperm to enter egg) than fertile eggs, and they are shorter and narrower than fertile eggs. She will also be using molecular techniques to identify the symbiotic bacteria housed in the gut of Sehirus cinctus cinctus. This information will help sort out the phylogeny of this interesting group of insects.

Shazrah Syed is clarifying the preferred microclimate characteristics in the field for habitation of S. cinctus cinctus.

Miranda Figueras and Anthony LoMaestro examined the correlation between insect abundance and diversity in the Hempstead Plains and the abundance and variety of native vs invasive plants.

Miranda Figueras used SEM to characterize fertile and trophic eggs of Adomerus rotundus.
