The larva of Peristicta aeneoviridis Calvert, 1909 is described for the first time, based on material from Misiones Province, Argentina. It differs from the rest of the larvae described for the genus in the shape and coloration of caudal lamellae, femur setae, lacinia teeth and coloration patterns. Additions to the description of the larva of P. forceps Hagen in Selys, 1860 are included.

AbstractThe first instar larva of a species of the Australian endemic genus Aenigmetopia Malloch is described for the first time, along with the first instar larvae of three other Australian species representing the genera Amobia Robineau-Desvoidy and Protomiltogramma Townsend. Larval morphology was analysed using a combination of light microscopy, confocal laser scanning microscopy and scanning electron microscopy. The following morphological structures are documented: pseudocephalon, antennal complex, maxillary palpus, facial mask, modifications of thoracic and abdominal segments, anal region, spiracular field, posterior spiracles and details of the cephaloskeleton. Substantial morphological differences are observed between the three genera, most notably in the labrum and mouthhooks of the cephaloskeleton, sensory organs of the pseudocephalon, spinulation, sculpture of the integument and form of the spiracular field. The first instar larval morphology of Aenigmetopia amissa Johnston, Wallman, Szpila & Pape corroborates the close phylogenetic affinity of Aenigmetopia Malloch with Metopia Meigen, inferred from recent molecular analysis. The larval morphology of Amobia auriceps (Baranov), Protomiltogramma cincta Townsend and Protomiltogramma plebeia Malloch is mostly congruent with the morphology of Palaearctic representatives of both genera.

AbstractThe fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has become a major threat in maize cultivation since its invasion to India in 2018. The humpbacked fly, Megaselia scalaris (Loew) (Diptera: Phoridae), was recorded as a laboratory parasitoid of FAW, for the first time in India. Initially, 30–40 maggots of M. (M) scalaris emerged out from the dead pre-pupa and pupa of laboratory-reared FAW. The fly laid up to 15 eggs on the outer surface of 6th instar larva or pre-pupa of the FAW. The incubation period was 1–2 days. The fly had 3 larval instars which lasted 3–4 days and a pupal period of 10–11 days. The adults survived for 6–7 days.

Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

AbstractRecords of braconid parasitoids attacking bees (Apidae) are reviewed and their biology is discussed. The adult of Syntretomorpha szaboi Papp (Braconidae) is redescribed, the female for the first time. The final-instar larva is also described for the first time and the implications of interpreting larval characters are discussed. The Oriental honey bee, Apis cerana Fabricius, is recorded here for the first time as the host of S. szaboi.

The coffee bean weevil, Araecerus fasciculatus (De Geer) (Coleoptera: Anthribidae), is a cosmopolitan insect with >100 hosts, and has been reported as a pest of stored coffee. During a study involving the coffee berry borer, we observed coffee bean weevils emerging from field-collected coffee berries and used micro-computerized tomography (micro-CT) scans to observe the insect inside the berry. Two eggs had eclosed inside the berry, resulting in observations of a newly eclosed adult beetle and a 5th instar larva, each feeding on one of the two seeds. This is the first time since 1775, when the insect was first described, that the insect has been observed inside a coffee berry.

The Neotropical genus Leptagrion Selys is composed by 16 species, mainly distributed in northern and central South America (Costa & Garrison 2001; De Marmels & Garrison 2005; Lencioni 2006). Only phytotelmic habitats were recorded for its larvae, exclusively in bromeliads, e.g., Vriesia, Neoregelia, Quesnelia, Portea, Bilbergia, Canistrum, Aechmea (Santos 1966, 1968, 1978, 1979; Lounibos et al. 1987; Corbet 1999). However, no final stage larva of any species of Leptagrion has been described to date. De Marmels (1985) described that of L. fernandezianum Rácenis, but this species was transferred to the newly erected and related genus Bromeliagrion De Marmels in De Marmels & Garrison (De Marmels & Garrison 2005). In addition, Torreias et al. (2008) described the final instar larva of B. rehni Garrison from Guzmania bromeliads. Leptagrion andromache Hagen in Selys belongs to the porrectum species group and was previously recorded from Brazil (Espirito Santo) (Costa & Garrison 2001; Lencioni 2006). In this paper we describe the final instar larva of L. andromache based on reared specimens of both sexes collected in Misiones province, Argentina and we compare them with that of B. fernandezianum and B. rehni.

The comparactive morphology of the male and female postabdomen of the Australian Tachinidae was studied in a survey which included 152 species of representative genera from all subfamilies except Dufouriinae. The value of the structure of the postabdomen for the higher classification of the family was ascertained, and new information gained which has allowed a better understanding of the correct taxonomic position of some problem groups of tachinids. It was possible to recognise suites of characters for each sex to define each subfamily, but this was not possible at tribal or generic levels in most groups. The male terininalia are diagnostic at specific level. The survey also allowed the discovery of, or confirmed, the reproductive habit of the included genera and provided information on the first-instar larva of 52 species, many of which larvae are described below for the first time. Characters of puparia which may have taxonomic value are discussed and illustrated.

Abstract The puparium of Cyphomyia albitarsis (Fabricius, 1805) is described and illustrated for the first time, based on six puparia, of which five emerged into adults. In Cyphomyia Wiedemann, 1819, the immature stages (6th instar larva or puparia) of only eight species are known (Cyphomyia aurifrons Wiedemann, 1830, C. bicarinata Williston, 1900, C. erecta Mc-Fadden, 1969, C. leucocephala Wiedemann, 1819, C. marginata Loew, 1866, C. picta Schiner, 1868, C. pilossisima Gerstaecker, 1857, and C. souzalopesi Iide, 1967), which represents only 9% of the Cyphomyia species described. In addition, some features of the previously known immature stages of the genus are summarized and compared with the puparium of C. albitarsis.

Abstract In this contribution we describe and illustrate for the first time, detailed morphology and chaetotaxy of the last instar larva and the pupa of Ora depressa (Fabricius, 1801), and provide diagnostic characters and information on its biology. The last instar larva of O. depressa exhibits the characters traditionally recognized as diagnostic of the genus, i.e. the tip of the mandible obtuse, and the fourth maxillary palpomere long, almost as long as third palpomere. Ora depressa is characterized by a broadly elliptical body, which is widest at the metanotum, being brownish testaceous in color with several brown spots, having the dorsal surface mostly covered with numerous grooved scale-like setae and also several ungrooved scale-like setae, hair-like setae, club-like setae and pore-like sensilla distributed in a specific pattern, and the femur and tibiotarsus bearing a row of natatorial setae. The last instar larva of Ora depressa can be distinguished from those of the other known species of the genus by lobes of clypeolabrum being as long as wide and socket bristles with 2–6 inner teeth. The pupa of O. depressa differs from those of the other known species of the genus in the absence of pronotal horns and by the place where pupation occurs. Ora depressa pupates underwater, hanging from water’s surface with the aid of the laterally expanded pronotum which bears hydrophobic setation along the lateral margins.
