Remarkable Aquatic Predators in the Genus Ocyptamus (Diptera, Syrphidae)
ROTHERAY et al.: 385-389 Studia dipterologica 7 (2000) Heft 2 • ISSN 0945-3954 Remarkable aquatic predators in the genus Ocyptamus (Diptera, Syrphidae) [Bemerkenswerte aquatische Pradatoren in der Gattung Ocyptamus (Diptera, Syrphidae)] by Graham E. ROTHERAY, Manuel ZUMBADO, E. Geoffrey HANCOCK and F. Christian THOMPSON Edinburgh (United Kingdom) Santo Domingo (Costa Rica) Glasgow (United Kingdom) Washington (USA) Abstract Third-stage larvae, puparia and adults are described for two species of Ocyptamus MACQUART and new synonyms are proposed. The larvae were found in water pockets within epiphytic Bromeliaceae in Costa Rica. They attacked a wide taxonomic range of insect larvae that char- acteristically co-occur in these phytotelmata, apparently subduing prey with venom and suck- ing out the internal contents. They possess a number of morphological and behavioural fea- tures not known in other predatory syrphids. These features include an enlarged and flattened anal end bearing a sucker, elongate posterior breathing tubes with vertically inclined spiracu- lar plates, and patches of needle-like spicules on the underside of the thorax. Although only two species were reared, larvae of 6 other species were discovered, which suggest that many more species occur in bromeliads. Key words Predator, phytotelmata, bromeliads, anal sucker, venom Zusammenfassung Von zwei Arten der Gattung Ocyptamus MACQUART werden die dritten Larvenstadien, die Puparien und die Imagines beschrieben und charakterisiert sowie neue Synonyme festgelegt. Die Larven wurden in Phytothelmata von epiphytischen Bromelien in Kostarika gefunden. Sie attackieren ein weites Spektrum von Insektenlarven, die hier gemeinsam mit den Syrphiden- larven leben. Offensichtlich lahmen sie die Beute mittels eines Giftes und saugen dann den deren Korperinhalt aus. -
Larval Dispersal Behaviour and Survival on Non-Prey Food of The
Ecological Entomology (2018), 43, 578–590 DOI: 10.1111/een.12636 Dealing with food shortage: larval dispersal behaviour and survival on non-prey food of the hoverfly Episyrphus balteatus ILKA VOSTEEN,∗ JONATHAN GERSHENZON and GRIT KUNERT Department of Biochemistry, Max-Planck Institute for Chemical Ecology, Jena, Germany Abstract. 1. Predatory larvae often have to face food shortages during their develop- ment, and thus the ability to disperse and find new feeding sites is crucial for survival. However, the dispersal capacity of predatory larvae, the host finding cues employed, and their use of alternative food sources are largely unknown. These aspects of the foraging behaviour of the aphidophagous hoverfly (Episyrphus balteatus De Geer) larvae were investigated in the present study. 2. It was shown that these hoverfly larvae do not leave a plant as long as there are aphids available, but that dispersing larvae are able to find other aphid colonies in the field. Dispersing hoverfly larvae accumulated on large aphid colonies, but did not distinguish between different pea aphid race–plant species combinations. Large aphid colonies might be easier to detect because of intensified searching by hoverfly larvae following the encounter of aphid cues like honeydew that accumulate around large colonies. 3. It was further shown that non-prey food, such as diluted honey or pollen, was insufficient for hoverfly larvae to gain weight, but prolonged the survival of thelarvae compared with unfed individuals. As soon as larvae were switched back to an aphid diet, they rapidly gained weight and some pupated after a few days. Although pupation and adult hatching rates were strongly reduced compared with hoverflies continuously fed with aphids, the consumption of non-prey food most probably increases the probability that hoverfly larvae find an aphid colony and complete their development. -

Phylogeny of Syrphidae (Diptera) Inferred from Combined Analysis of Molecular and Morphological Characters
Systematic Entomology (2003) 28, 433–450 Phylogeny of Syrphidae (Diptera) inferred from combined analysis of molecular and morphological characters GUNILLA STA˚HLS1 , HEIKKI HIPPA2 , GRAHAM ROTHERAY3 , JYRKI MUONA1 andFRANCIS GILBERT4 1Finnish Museum of Natural History, University of Helsinki, Finland, 2Swedish Museum of Natural History, Stockholm, Sweden, 3National Museums of Scotland, Edinburgh, U.K. and 4School of Biological Sciences, Nottingham University, Nottingham, U.K. Abstract. Syrphidae (Diptera) commonly called hoverflies, includes more than 5000 species world-wide. The aim of this study was to address the systematic position of the disputed elements in the intrafamilial classification of Syrphidae, namely the monophyly of Eristalinae and the placement of Microdontini and Pipizini, as well as the position of particular genera (Nausigaster, Alipumilio, Spheginobaccha). Sequence data from nuclear 28S rRNA and mitochondrial COI genes in conjunction with larval and adult morphological characters of fifty-one syrphid taxa were analysed using optimization alignment to explore phylogenetic relationships among included taxa. A species of Platypezidae, Agathomyia unicolor, was used as outgroup, and also including one representative (Jassidophaga villosa) of the sister-group of Syrphidae, Pipunculidae. Sensitivity of the data was assessed under six different parameter values. A stability tree sum- marized the results. Microdontini, including Spheginobaccha, was placed basally, and Pipizini appeared as the sister-group to subfamily Syrphinae. The monophyly of subfamily Eristalinae was supported. The results support at least two independ- ent origins of entomophagy in syrphids, and frequent shifts between larval feeding habitats within the saprophagous eristalines. Introduction At the beginning of the last century, Syrphidae was divided into 2–20 subfamilies by different authors. -

Author: Reemer, Menno Title: Unravelling a hotchpotch : phylogeny and classification of the Microdontinae (Diptera: Syrphidae) Issue Date: 2012-03-13 7 Review and phylogenetic evaluation of associations between Microdontinae (Diptera: Syrphidae) and ants (Hymeno- ptera: Formicidae) Abstract. The immature stages of hoverflies of the subfamily Microdontinae (Diptera: Syrphidae) are known to develop in ants nests, as predators of the ant brood. The present paper reviews published and unpublished records of associations of Microdontinae with ants, in order to discuss the following questions: 1. are alle Microdontinae associated with ants?; 2. are Microdontinae associated with all ants?; 3. are particular clades of Microdontinae associated with particular clades of ants? A total number of 103 records of associations between the groups are evaluated, relating to 42 species of Microdontinae belonging to 14 (sub)genera, and to 58 species of ants belonging to 23 genera and four subfamilies. Known associations are mapped onto the most recent phylogenetic hypotheses of both ants and Microdontinae. The taxa of Microdontinae found in association with ants appear to occur scattered throughout their phylogenetic tree, and one of the supposedly most basal taxa (Mixogaster) is known to be associated with ants. This suggests that associations with ants evolved early in the history of the subfamily, and have remained a predominant feature of their lifestyle. When considering the phylogeny of ants, associations with Microdontinae are only known from the subfamilies Dolichoderinae, Formicinae, Myrmicinae and Pseudomyrmecinae, which are all part of the the so-called ‘formicoid’ clade. -

However, there have been no reports regarding the observation of immature stages of this species in association with P. lamellidens. New information For thefirst time, we found three M. katsurai larvae inside a P. lamellidens nest and conducted rearing experiments on the larval M. katsurai. P. lamellidens workers did not show any inspection or attack behavior against the M. katsurai larvae under rearing conditions, suggesting that M. katsurai larvae can survive inside a P. lamellidens nest. Although no predatory behavior by the M. katsurai larvae was observed, all the M. -
