The light-attracted silk moths (Lepidoptera: Saturniidae) of the Boraceia Biological Station in the municipality of Salesópolis, state of São Paulo, southeastern Brazil have been sampled over more than seven decades (1942-2013). A total of 6,288 individuals (including a gynandromorph) belonging to five subfamilies, 46 genera and 133 species were identified. Hemileucinae was the most abundant and speciesrich subfamily, followed by Ceratocampinae, Arsenurinae, Saturniinae, and Oxyteninae. Hylesia Hübner, Automeris Hübner, and Dirphiopsis Bouvier (Hemileucinae) were the dominant genera in abundance and species richness. Only Automeris illustris (Walker), Gamelia remissoides Lemaire, and Hidripa paranensis (Bouvier) (Hemileucinae) were recorded in all months of sampling. Hylesia metapyrrha (Walker) was the most abundant saturniid species recorded at the station, with 375 specimens, followed by Hylesia oratex Dyar with 265 specimens, Dirphia muscosa Schaus with 261 specimens (all Hemileucinae); Copaxa canella Walker (Saturniinae) with 232 specimens, and Lonomia cf. obliqua Walker (Hemileucinae) with 106 specimens. Fifteen additional species were each represented by more than 100 specimens. The importance of the Boraceia Biological Station to the maintenance of the saturniid moth diversity in the Atlantic Forest is discussed.

Species of Macrosiagon Hentz are known to be wasp and bee parasitoids. Here, we present information on Macrosiagon octomaculata (Gerstaecker, 1855), including eggs and triungulinids, found on Paepalanthus polyanthus (Bong.) Sano (Eriocaulaceae) blooming in restinga habitat on Santa Catarina Island, South Brazil. This is the first record of an Eriocaulaceae species playing an important role in the Macrosiagon bionomics and the first accurate record of Ripiphoridae for southern Brazil, Santa Catarina state. In the study area, P. polyanthus attracted an inordinate number of insect species and one Thynnidae wasp was captured with a triungulinid on its wing. Eggs and triungulinids were also found on one plant of P. polyanthus and associated with M. octomaculata. We provide descriptions of the female reproductive organs as well as the morphology of the triungulinid of M. octomaculata. A detailed examination of the triungulinid revealed novelties that complement information from previous publications regarding the Ripiphoridae. We also compare triungulinids of M. octomaculata with those of other species, and provide a table summarizing comparative characters. Finally, we provide a table with current information on the recorded host species and immatures of Macrosiagon.

The third instar larvae and the pupae of Platyphileurus felscheanus Ohaus, 1910 (Phileurini), recently synonymized with Surutu jelineki Endrődi, 1975 (Cyclocephalini), are described and illustrated, and some life history information is given. The larvae were collected and reared in bromeliads in rain forests of Santa Catarina state in southern Brazil. The systematic position of this monotypic genus is reassessed at the tribe level by considering larval and adult morphological characters. Both character sets, being described and illustrated, suggest the placement of Platyphileurus in the tribe Oryctini.

Immatures of the Phelypera schuppeli (Boheman, 1834) (Curculionidae; Hyperinae; Cepurini) are described, illustrated and compared with available descriptions of larvae and pupae of Hyperini. Immatures and adults from midwest (Dourados, Mato Grosso do Sul; Pirenópolis, Goiás) and southeast Brazil (Bauru, São Paulo) were found on leaves of the host plant, Pachira aquatica Aubl. ( Malvaceae, formerly Bombacaceae), a tree used as an ornamental plant in many Brazilian frost-free cities. Larvae of P. schuppeli are exophytic, brightly colored, eruciform and possess abdominal ambulatory ampullae, resembling larvae of Lepidoptera. Mature larvae can spin globular lattice-like cocoons where pupation takes place. Data in the field and under laboratory conditions confirmed previously published biological observations on P. schuppeli. Additional information about defensive behaviors, process of cocoon construction and natural enemies, such as the larval predator Supputius cinticeps (Stål, 1860) (Hemiptera: Pentatomidae) and the prepupal and pupal parasitoid Jaliscoa nudipennis Bouček, 1993 (Hymenoptera: Pteromalidae), are reported.

The first instar larva of Atractocerus brasiliensis (Lepetelier & Audinet-Serville, 1825)

The stick insect Paraphasma paulense was described based on one male from the vicinity of São Paulo city, state of São Paulo, Brazil. Here we describe and illustrate the female, egg and first instar nymph of the species, including scanning electron micrographs of the egg. In addition, we give brief behavioural reports and present a few comments on the biology and morphology of P. paulense.
