Cephalocera catulus Gerstaecker, 1868
endemic

Morphological description

Hesse (1969) redescribed this species as follows: Head with antennal segment-3 according to Gerstaecker distinctly longer, more than 3 times combined length of 1 and 2 (in C. namaquensis it is only a little more than twice this length); interocular space on vertex, according to the figure, appears to be distinctly broader; proboscis relatively shorter, about twice vertical length of eyes (in C. namaquensis distinctly more than twice this length).Wings with the veins darker, more brownish, not yellowish as in C. namaquensis. Abdomen with hind margins of tergites 2-7 more yellowish reddish, not mainly whitish; bands of whitish or silvery tomentum across tergites 3-7 evidently broader, more broadly triangularly produced towards base than in C. namaquensis. Legs pale yellowish brownish and hind femora darkened above (in C. namaquensis with the front and middle legs paler, more yellowish and hind femora and tibiae uniformly castaneous brownish); hind femora, according to figure, less spindle-shaped incrassate; hind tibiae not so markedly shortish and, according to the figure, not distinctly produced apically. Vestiture with the hairs on thorax above reddish brownish, more golden-yellowish on sides (those on disc in C. namaquensis whitish and pale fulvous-brownish, those on sides dense and contrastingly snow whitish); hairs at base of abdomen greyish yellowish, not snow-whitish.

Diagnostic description

This species differ from C. namaquensis in the several respects noted in the morphological description.

Movement

The information below was extracted from Cannings and Scudder (2005): Dipterans are primarily aerial insects and the mesothorax, which bears the only pair of wings, dominates the thorax - the prothorax and metathorax are greatly reduced. The legs are normally rather simple and are used primarily for perching; in some groups, they are modified for prey capture or for signaling during courtship. The tarsi are nearly always 5-segmented. The functional wings are membranous and their pattern of veins is critical in fly classification and identification. During the evolution of flies, there has been a trend towards a reduction in veins, especially in the rear half of the wing – changes that evidently relate to improvements in two-winged flight. The hindwings, present in most other insects, are reduced in Diptera to small, club-like organs, called halteres, used for stabilising flight.

Trophic level

Herbivore - Nectarivore (nectar-eating)

Trophic strategy

The flies in this family are not known to hunt, catch or prey upon other insects as asilids do. They are however known to imbibe on the flower nectar especially Afroleptomydas and Cephalocera. These species sometimes visit flowers, especially those of species of Mesembryanthemum (Hesse 1969).

Reproduction

Like the others, flies in the Mydidae family begin life as an egg, which hatches into a grub-like larva. Most of the fly life is spent in the larval stage, mainly eating and growing as well as molting several times. Some flies may spend at least a year as a larva. The next stage is a pupa, during which the insect transforms into its final stage, emerging from the pupa as a winged adult, able to mate and reproduce. In many species, males stake out positions at favourable egg-laying sites and wait for females to arrive (Hesse 1969).
