ABSTRACT The muscid Hydrotaea cyrtoneurina (ZETTERSTEDT, 1845) is a Palaearctic species whose adults are known for their forensic importance. The third instar larva morphology of H. cyrtoneurina, hitherto unknown, is described herein with the application of light and scanning electron microscopy. The characters of larval morphology enabling this species to be distinguished from other forensically important third instar larvae of Muscidae are discussed as well. Some details of the cephaloskeleton are discussed, and modifications in terminology are proposed based on the literature data and the results of this study.

Abstract The flower- or hoverflies (Syrphidae) and particularly the subfamily Eristalinae, are known by their importance as pollinators in both natural and agro-ecosystems. Similar to other saprophagous eristalines, the larvae of Eristalis Latreille, 1804 are characterized by an elongated anal segment and a telescopic breathing tube. These features have given them the common name of rat-tailed maggots and allow them to develop in liquid or semi-liquid media loaded with decaying organic material. This paper presents the first description of the egg and the third-instar larva of the boreal species Eristalis fratercula (Zetterstedt, 1838). Morphological studies are presented based on cryo-scanning electron microscopy (cryo-SEM). After comparison with all other known species of the genus Eris-talis with described preimaginal morphology, we conclude that main diagnostic character of E. fratercula is the presence of long branched spicules located in the upper margin on the lateral lips. Finally, we provide an updated key that includes the 15 Eristalis species whose third larval stages have already been described.

The Palaearctic genus Trichomeloe is reviewed and newly defined on the basis of larval and adult characters. Its position among the Lyttini tribe is discussed. Trichomeloe includes eight species, mostly from the Near East. The bionomics of the genus is summarized, together with a key to the species, an annotated catalogue and some taxonomic remarks. T. syriacus n. sp. from Syria and T. mesopotamicus n. sp. from northern Irak, are described. The first instar larva of T. syriacus is described and compared with that of T. chrysocomus, both figured by scanning electron microscopy photographs.

The morphology and chaetotaxy of the first instar larva of the scorpionfly Sinopanorpa tincta (Navás, 1931) are described and illustrated for the first time with the aid of light microscopy and scanning electron microscopy, with particular attention to the mouthparts and their sensilla. A comparison is made with the larvae of other known Mecoptera, especially Panorpa and Neopanorpa in Panorpidae.

ABSTRACT The biology and morphology of the immature stages of Heliconius sara apseudes (Hübner, [1813]) are still little known. External features of the egg, larvae and pupa of H. sara apseudes are described and illustrated, based upon light and scanning electron microscopy. Eggs with smooth carina, first instar larva with scaly setae, and body of second to fifth instars covered with scattered pinnacles distinguish H. sara apseudes from other heliconiine species.
