''Ogcodes'' is a cosmopolitan genus of small-headed flies in the family

Acroceridae The Acroceridae are a small family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common ...

. About 90 species have been described for the genus. It is the most common and speciose genus in its family. These flies are endoparasitoids of ground-dwelling entelegyne spiders.

Characteristics

Flies in this genus can be distinguished from other genera in the family

by the following combination of characteristics: * Antennae positioned on the ventral surface of the head, slightly above the mouth *Tibiae lacking apical spurs *Eyes always holoptic *Short, rod-like antennal flagellum *Mouthparts hidden by a membrane *Reduced wing venation Adult ''Ogcodes'' are small to medium in size, with rounded heads and abdomens. They are often brown or black in color, with a pale horizontal band at the posterior edge of each abdominal tergite.

Life History

Soon after mating, females lay their eggs around dead twigs. These eggs are brown or black in color, and usually under 0.35 millimeters in length. Larvae are endoparasitoids in spiders. Upon emerging, planidial larvae wait to come in contact with a host spider. If a host is not found, the larvae can move to nearby sites by springing into the air or moving similarly to an inchworm. If a host is found, the larva will typically enter it through the abdomen, or occasionally through the intersegmental membranes of the legs. Upon attaching to the inside of the host, the larva will molt twice at a rate that depends on the developmental pace of the host. The site of attachment is in an air pocket between the lamellae of the spider's book lungs. The third-instar larva will consume most of the host spider’s internal contents, then emerge by making a hole along the host’s epigastric furrow. Evidence that acrocerid flies deliberately influence host behavior is limited, but flies in this genus have been observed emerging shortly after their hosts create webbing and clinging to the new webbing using adhesives on their bodies. One to three days after emerging, the larva pupates. Adults can be encountered around dead twigs, or in grassy, wet areas. They have not been observed feeding, though it is possible that the oral membrane in place of functioning mouthparts may be used to collect moisture from the air. Adults are thought to live for three to four weeks at maximum in nature.

Hosts

Larval ''Ogcodes'' have been documented developing in spiders from the following taxonomic families: *

Like many acrocerids, planidial ''Ogcodes'' tend to target hosts that wander or build webs on the ground. Several species within the genus can develop in spiders from three or more different taxonomic families, namely '' O. adaptus'', '' O. dispar'', '' O. eugonatus'', and '' O. pallidipennis''.

Distribution

''Ogcodes'' as a whole is cosmopolitan in distribution. Species richness in ''Ogcodes'' is highest in Australia and the Nearctic and Palearctic regions. Species in this genus have not been collected from deserts and certain islands, such as Madagascar and Iceland. The majority of species are found in only one geographic region, with the exceptions of '' O. pallidipennis'', '' O. dispar'', and '' O. guttatus''. Alongside ''

. While many species in Acrocerinae target haplogyne spiders, not a single species in ''Ogcodes'' does. Despite sharing morphological characteristics with the acrocerid genus ''

'', such as having antennae located on the ventral surface of the head and reduced mouthparts, molecular data indicates that these two genera are not particularly closely related.

Subgenera and species
