Mexican Snake-Flies (Neuroptera: Raphidiodea)

Ovariole development in telotrophic ovaries of snake flies (Raphidioptera).

Snake flies (Raphidioptera), alder flies (Megaloptera: Sialidae) and also some myxophagan coleopterans share the same, peculiar telotrophic organization of their ovarioles usually referred to as ovarioles of the Sialis-type. Ovariole ontogenesis in Raphidia sp. is described and the basic events that lead to the formation of germ cell clusters and their subsequent transformations are reported. I...

Volatile Semiochemicals Increase Trap Catch of Green Lacewings (Neuroptera: Chrysopidae) and Flower Flies (Diptera: Syrphidae) in Corn and Soybean Plots

This study reports on the attractiveness of volatile chemicals to green lacewings (Neuroptera: Chrysopidae) and flower flies (Diptera: Syrphidae) as measured by catch on yellow sticky traps within corn [Zea mays L. (Cyperales: Poaceae)] and soybean [Glycine max (L.) Merr. (Fabales: Fabaceae)] plots. Green lacewings were attracted to eugenol-baited traps in two tests in soybean plots. Follow-up ...

Morphological convergence in a Mexican garter snake associated with the ingestion of a novel prey

Morphological convergence is expected when organisms which differ in phenotype experience similar functional demands, which lead to similar associations between resource utilization and performance. To consume prey with hard exoskeletons, snakes require either specialized head morphology, or to deal with them when they are vulnerable, for example, during molting. Such attributes may in turn red...

Intraspecific variation in the diet of the Mexican garter snake Thamnophis eques (#18690)

Insecta Neuroptera, Megaloptera e Raphidioptera

Neuroptera are holometabolous insects of small to medium size (in few cases large); their are over 6,500 estimated species worldwide, belonging to 37 orders (or suborders, according to the views of various authors): Megaloptera, Raphidioptera and Neuroptera sensu stricto. The Italian fauna is relatively well known thanks to works specifi cally aimed at this group, particularly following the rev...
