Stelis australis floridensis

(Mitchell, 1962)

Stelis australis floridensis is a of cleptoparasitic in the Megachilidae. It was described by Mitchell in 1962. Like other members of the Stelis, this bee is a kleptoparasite (cuckoo bee) that lays its in the nests of other bees, primarily megachilid . The subspecific epithet 'floridensis' indicates its association with Florida. Very few observations of this have been recorded.

Identification

As a member of the Stelis, this likely exhibits the characteristic compact, somewhat flattened body form typical of cleptoparasitic megachilids. Stelis generally have reduced scopal structures compared to their , as they do not collect pollen for their own offspring. Specific diagnostic features distinguishing S. a. floridensis from the nominate subspecies and other Stelis would require examination of and detailed morphological study.

Distribution

Florida, United States. The subspecific epithet and limited observation records indicate this is a Florida- or Florida-associated of the more widely distributed Stelis australis.

Diet

likely feed on nectar from flowers. As a , larvae consume the pollen provisions and developing larvae of bees rather than collecting food independently.

Host Associations

Megachilidae - Stelis are specialized of other megachilid bees, though specific records for this are not documented in available sources.

Life Cycle

As a cleptoparasitic , the involves the female entering nests to deposit . The Stelis larva typically kills the host egg or larva and consumes the stored pollen provisions. Development occurs within the host , with the emerging from the host nest.

Behavior

Cleptoparasitic is characteristic of the . Females are expected to locate nests and deposit during the activity period of their megachilid hosts.

Ecological Role

Acts as a in , potentially influencing of its megachilid . This parasitic relationship represents a natural component of native bee community structure.

More Details

Taxonomic note

This was established by Mitchell in 1962. The Stelis contains numerous and subspecies, many of which are poorly known and rarely collected. The limited number of iNaturalist observations (2 records) suggests this is either genuinely rare, under-collected, or difficult to identify from photographs.

Data limitations

Available sources provide minimal biological information specific to this . Most aspects of its are inferred from the -level characteristics of Stelis.
