Trap-nesting biology of an ectoparasitoid spider wasp, Auplopus subaurarius (Hymenoptera: Pompilidae): the importance of wooded environments for niche generalist species.

The insect group is one of the most diverse on the planet and due to habitat degradation, many of these species are becoming extinct, leaving a lack of information on the basic biology of each one. In this study, previously unseen information about nesting biology is revealed in Auplopus subaurarius trap nests. This is a solitary ectoparasitoid spider wasp that nests in preexisting cavities.

Nesting Biology of the Potter Wasp Ancistrocerus flavomarginatus (Hymenoptera, Vespidae, Eumeninae) Revealed by Trap-Nest Experiments in Southern Brazil.

This paper provides the first description of the nesting biology of Ancistrocerus flavomarginatus (Brèthes) (Hymenoptera, Vespidae, Eumeninae), the only species of the genus found in Brazil. Our trap-nest experiments were conducted in two Mixed Ombrophilous Forest fragments and two adjacent matrices in Guarapuava (Paraná state, Brazil) from August 2017 to July 2018. In each area, we set 192 trap nests divided into six groups of 32 units, totalling 768 trap nests.

Description of the male, nest architecture and biology notes of Zethus plaumanni Bohart amp; Stange, 1965 (Hymenoptera, Vespidae) in southern Brazil.

Although diverse and widespread, there is much to improve on the knowledge of Zethus Fabricius, 1804 wasps. This includes aspects of many areas, such as data on taxonomy, behavior and biology. In the present study, we investigated Zethus plaumanni Bohart Stange, 1965, a species hitherto known only from the female type in the literature, and worked to fill gaps on the knowledge of this species by describing the male and its genitalia, the nest structure and giving notes on the biology of individuals collected in trap-nests in southern Brazil.

Nesting Biology of the Solitary Wasp (Hymenoptera, Crabronidae, Trypoxylini) in a Neotropical Hotspot of Southern Brazil.

is a specie of solitary wasp that builds its nests in pre-existing cavities; it has only been recorded nesting in the Araucaria forest, one of the Atlantic forest phytophysiognomies and a biodiversity hotspot. So far, the only information on the biology of the genus is based on one species. In addition, the genus has many similarities to , showing an increased need for studies on the biology of these species of wasps.

Description of the male of Suárez, 1960 (Hymenoptera, Mutillidae), including new information on the biology of the genus.

The male of Suárez, 1960 is described and associated with the female based on couples reared from trap-nests occupied by Dreisbach, 1963 (Hymenoptera: Pompilidae). Information on the diapause of and Pseudomethoca nr. chontalensis (Cameron, 1895) (Hymenoptera: Mutillidae) is presented.
