Antlion larvae Myrmeleon brasiliensis Návas, 1914 (Neuroptera, Myrmeleontidae) are sit-and-wait predators who build traps to catch their prey. The aim of this study was to observe under laboratory conditions, how the energy cost spent on maintenance of their traps affects: the larval developmental time, time spent as a pupa, mortality rate of larvae and adult size. M. brasiliensis larvae were c...

This survey presents an overall view of the order Neuroptera from Brazil. A total 432 valid extant species divided into ten families, are recorded country. Among Brazilian fauna, 211 endemic (48.8%), with majority belonging to two families: Chrysopidae 182 in 19 genera, and Myrmeleontidae 88 25 genera. The first discovered Brazil was Climaciella semihyalina (Le Peletier & Audinet-Serville), 182...

Morphology and behaviour of third instar larvae of the Holomediterranean antlion species Myrmecaelurus trigranunus (Pallas) are described. Larvae are facultative pit-builders, they either ambush their prey at the surface, or dig pitfall traps that prey fall in to. Dark brown spots on dorsal and ventral sides of the head and on dorsal side of the thorax are characteristic of the larvae. Eye tube...
