“…Except for the aforementioned authors, no other workers have described or illustrated the sensory organ X in any of the muscid species. According to ZACHARUK & SHIELDS (1991), the sensory organ X is equipped with uniporous gustatory chemosensilla or chemo-mechanosensilla. Recent studies (PYTHON 2002) of the neuronal organization of sensilla in the third instar larva of Drosophila melanogaster MEIGEN, 1830 (Drosophilidae) confirmed the presence of sensilla in a position equivalent to KEILIN'S (1915) sensory organ X.…”

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.

Compared to other aquatic insect species (Gaino & Rebora, 1999), the absence of antennae in Lype might be interpreted as a consequence of a semi-sessile life per formance.…”

“…larvae indicate an important role in feeding. Sensilla on insect mouthparts are primarily contact gustatory or olfac tory receptors for checking the chemical composition of substrates and for detecting food resources (Zacharuk & Shields, 1991;Shields, 1996).

“…The number, distribution and function of sensilla on the mouthparts of terrestrial insect larvae play an important role in detecting feeding resources and evaluating their quality prior to ingestion (Zacharuk & Shields, 1991;Shields, 1996). We are, however, not aware of such studies on aquatic species.…”

Abstract. The larvae of Lypephaeopa (Stephens, 1836) are found on dead wood substrates in streams and lakes. Gut content analy ses, scanning electron microscopy of larval mouthparts, and gallery structure revealed characteristics of this habitat preference. The guts of the larvae contained mainly wood fragments whereas other food items (detritus, algae, fungi, inorganic particles) were much rarer. The suitability of the mouthparts to scrape wood surfaces, and the adaptative elongation of the silk-secreting spinneret, which facilitates the construction of retreats consisting of a tunnel-like silken net incorporating mainly wood fragments, are discussed. Retreat-construction under laboratory conditions indicated that larvae exploit new feeding areas by steadily extending their galleries.Tips of the maxillary palps bear five sensilla styloconica and five sensilla basiconica, almost all bearing an apical pore. Three sen silla styloconica, two with an apical peg, and two small inconspicious sensilla basiconica are located on the galea. Possible function of these sensilla is discussed on the basis of studies on the closely related sister-group of Lepidoptera.
