Synchronous nocturnal activity and gregarious roosting in the neotropical skipper butterfly Celaenorrhinus fritzgaertneri (Lepidoptera: Hesperiidae)

Gregarious roosting behaviour and nocturnal activity is virtually unknown within the family Hesperiidae. Observations on Celaenorrhinus fritzgaertneri (Bailey) from Guanacaste Province, Costa Rica, are presented which demonstrate that, during the dry season, individuals roost gregariously in cave-like situations during the day and are nocturnally active. Circadian behaviour is highly synchronized with regard to timing of departures and arrivals at the roosting site, and appears to be regulated by light levels. Individuals on the roost are in reproductive diapause and show marked roost-site fidelity and longevity. The break-up of roosts appears to be mediated by the onset of the first rains of the season. These observations are compared and discussed in relation to gregarious roosting in other Lepidoptera. Two possible life history strategies to explain roosting in C. fritzgaertneri , with appropriate experiments, are suggested for future studies.     

A phylogenetic investigation of the Neotropical genus Alphamenes van der Vecht, 1977 (Hymenoptera,Vespidae, Eumeninae)

Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systematics have been proposed in the last five years, including the genus Alphamenes. This taxon contains seven described species whose distribution is exclusively Neotropical. Females are morphologically homogeneous, and characters related to copulatory organs are useful in male diagnosis. This contribution forms the first phylogenetic approach to include all species of Alphamenes, hence the first to strongly test for group monophyly. Our cladistic results recovered Alphamenes as a monophyletic group supported by male genital features. Relationships among included species also rely upon genitalic characters, highlighting the importance of these attributes for eumenine systematics. Recent phylogenetic investigations applied to the Neotropical fauna of potter wasps represent desirable advancements towards a natural classification for the group.

A new subspecies and a new synonym of the genus Coladenia (Hesperiidae,Pyrginae) from China

The second subspecies of Coladenia buchananii (de Nicéville, 1889), viz. Coladenia buchananii separafasciata Xue, Inayoshi & Hu, ssp. n., is discovered from south Jiangxi Province and west Fujian Province, southeast China. External and genital characters of both male and female of this new subspecies are illustrated and described. Coladenia neomaeniata Fan & Wang, 2006, syn. n. is proposed to be a junior synonym of Coladenia maeniata Oberthür, 1896, and the distribution of this species is briefly discussed.     

Ultrastructure of antennal sensilla of four skipper butterflies in Parnara sp. and Pelopidas sp. (Lepidoptera,Hesperiidae)

Most species of Parnara and Pelopidas (Hesperiidae) are important pests of rice. In this study, the antennal morphology, types of sensilla, and their distribution of four skipper butterflies, including Parnara guttata (Bremer & Grey), Pa. bada (Moore), Pelopidas mathias (Fabricius) and Pe. agna (Moore), were observed using a scanning electron microscope. Six distinct morphological types of sensilla were found on the antennae of all of these species: sensilla squamiformia, sensilla trichodea, sensilla chaetica, sensilla auricillica, sensilla coeloconica, and Böhm sensilla. The sensilla trichodea are the most abundant sensilla among the four skipper butterflies, and the sensilla auricillica are confirmed on the antennae of butterflies for the second time. In addition, the possible functions of these sensilla are discussed in the light of previously reported lepidopteran insects, which may provide useful information for further study of the function of these antennal sensilla and for related pests control by applying sex pheromones.     

Little-known accessory glands in female Zygaena moths (Lepidoptera, Zygaenidae)

In the female genital system of Zygaena moths, an additional pair of accessory glands is present besides the Y-shaped sebaceous gland. The term 'Petersen's glands' is proposed for these organs. Anatomy, histology, histochemistry and cytology of Petersen's glands of Zygaena trifolii are described. The sac-like glands, situated in the extreme dorsocaudal part of the abdomen, can be divided into a purely secretory part consisting of acini with large pear-shaped gland cells and a reservoir part with combined secretory and storage function. The secretory cells of the acini are penetrated by long curved ductules or secretory end apparatuses having feltwork consisting of very fine filaments. The cytoplasm is characterized by abundance of smooth tubular endoplasmic reticulum (ATER) and the presence of peroxisomes. This cytoplasmic organization is in accordance with the chemical composition of the sticky secretion, which evidently consists completely of lipids. The ultrastructure of the epithelium lining the reservoir of the glands has both traits of secretory and of transporting epithelia. Besides contributing to the secretion, it may be involved in absorption of residual aqueous phase from the contents of the reservoir.     

Male larval nutrition in Choristoneura rosaceana (Lepidoptera: Tortricidae): an important factor in reproductive success

This study examines how Choristoneura rosaceana male quality, as determined by larval diet, age and mating history, affects the reproductive success of both sexes. While the size of the spermatophore produced at first mating increased linearly with male age, the frequency of mating was significantly higher for middle-aged males (2–4 days old) than younger (0–2 days old) or older (6–8 days old) individuals, when both sexes were fed on artificial diet. However, the duration of copulation was longer in couples with older than younger males. The observed age-related changes in spermatophore size had no significant effect on female longevity, fecundity or fertility, suggesting no direct relationship between male investment and spermatophore size under these experimental conditions. Different larval food sources (artificial diet, maple and hazelnut) did not affect the proportion of 2-day-old virgin males that mated; however, the proportion that remated was significantly higher for males reared on high-quality food (maple and artificial diet) than those on hazelnut, a poorer food source. There was a 5-fold decline in spermatophore size between the first and second matings on all diets, but female reproductive output was reduced by only 25%. In contrast, while the first spermatophore produced by males on hazelnut was 1.5 times smaller than those produced on maple and artificial diet, the fecundity of their mates was 40% less than those mated with high-quality virgin males. These results provide additional support to the idea that spermatophore size is not a valuable indicator of male quality. Most tethered females placed in the field during the first flight period mated with virgin males (based on the size of the spermatophore), suggesting that female choice exists in this species. These results are discussed in relation to the incidence of polyandry in naturally occurring populations of Choristoneura and the potential use of size and/or chemical cues by females to assess male quality.     

Piloting the use of DNA barcoding in support of natural enemy surveys: New parasitoid records for banana skippers (Erionota spp., Lepidoptera,Hesperiidae) in Malaysia

We report a preliminary study carried out in Peninsular Malaysia, with the objective of rearing parasitoids of the two species of banana skippers (Erionota thrax and E. torus: Lepidoptera, Hesperiidae) and using DNA barcoding of Erionota spp. early stages (which are indistinguishable) and host remains to associate parasitoids with their host Erionota species. We were able to use barcodes to reliably identify the dead host remains, unreliably identify a limited subset of associated material (exuviae, frass, pupal exoskeleton, silk, wax) and to make provisional generic identifications of the parasitoids. We found parasitism by Argyrophylax sp. possibly phoeda (Tachinidae) on both species of Erionotus, by ?Casinaria sp. (Ichneumonidae) on E. thrax, and by Elasmus sp. (Eulophidae) on E. torus. The first is a new host-parasitoid association, and the second is a new association for Peninsular Malaysia. We conclude that the use of DNA barcoding, particularly for recently dead host remains, is a valuable tool to assess host-parasitoid associations where the hosts cannot be reliably identified from morphological characters.
