Morphology of Axymyia furcata (Diptera: Axymyiidae), including scanning electron microscopy of all life stages

  • Matthew W. Wihlm (a1), Rebecca B. Sam (a1) and Gregory W. Courtney (a1)

The morphology of all life stages of the semi-aquatic nematocerous fly, Axymyia furcata McAtee (Diptera: Axymyiidae), is documented, with emphasis on use of scanning electron microscopy (SEM). Our data on some life stages (e.g., egg, first-instar larvae) represent the first SEM examination of these stages in axymyiids. Among the unexpected results is absence of an egg burster in first instars. Most characters provided little evidence of a phylogenetic relationship with any other clade of nematocerous Diptera, reflecting a need for comprehensive morphological studies of the immatures of many families.


Nous présentons des informations sur la morphologie de tous les stades du cycle biologique de la mouche nématocère semi-aquatique Axymyia furcata McAtee (Diptera: Axymyiidae) principalement à l'aide de microphotographies au microscope électronique à balayage (SEM). Nos données sur certains stades du cycle (par ex., l'oeuf, les larves de premier stade) représentent le premier examen au SEM de ces stades chez les axymyiidés. Parmi les découvertes inattendues, il y a l'absence de ruptor ovi (dent d’éclosion) chez les larves de premier stade. La plupart des caractères fournissent peu d'indications de relations phylogénétiques avec les autres clades de diptères nématocères, ce qui souligne la nécessité d’études morphologiques détaillées des stades immatures de plusieurs des familles.
