Sphecodes heraclei ignitus

Cockerell, 1922

Fiery Cyclops Blood Bee

Sphecodes heraclei ignitus is a of blood bee within the Halictidae. Like other members of the Sphecodes, this is a (cuckoo bee) that exploits the nests of other solitary bees. The subspecific epithet 'ignitus' (meaning 'fiery') and its suggest distinctive coloration. The was described by Cockerell in 1922. As a Sphecodes, it exhibits the characteristic parasitic lifestyle of the genus, targeting sweat bees and other ground-nesting halictids.

Identification

This can be distinguished from other Sphecodes by the combination of its 'fiery' or reddish-orange coloration (referenced in both the subspecific name 'ignitus' and 'Fiery Cyclops Blood Bee') and specific morphological features characteristic of Sphecodes heraclei. Members of Sphecodes typically exhibit red and black coloration, reduced scopal hairs (since they do not collect pollen), and relatively slender bodies compared to their . The 'Cyclops' element of the common name may refer to facial markings or structure, though this requires verification. Separation from other Sphecodes subspecies and depends on subtle morphological differences in punctation, color pattern, and genitalia.

Host Associations

Life Cycle

As a cleptoparasitic , the involves the female entering the nest of a bee (typically a ground-nesting halictid) and depositing an in a provisioned . The Sphecodes larva hatches and consumes the host's pollen-nectar provision, then kills and consumes the host egg or larva. The parasitic larva completes development within the host cell, emerging as an the following season. This mirrors the general Sphecodes life cycle pattern, though specific timing for this is undocumented.

Behavior

Female Sphecodes heraclei ignitus has been observed hovering low to the ground near nest , searching for unguarded burrow entrances. This is characteristic of the : females wait for host bees to leave their nests, then quickly enter to deposit . Some Sphecodes have been reported to use force when encountering host resistance, including killing hosts and removing them from the nest entrance. Males are not involved in nest and are typically observed visiting flowers or patrolling nesting areas in search of mates.

Ecological Role

As a , this functions as a regulator of its . By parasitizing ground-nesting sweat bees, it influences host and may affect local pollination services indirectly through host suppression. Its presence indicates healthy populations of host bees and suitable nesting . The bee contributes to the diversity of the bee and represents an evolutionary success of the parasitic strategy within Halictidae.

Human Relevance

This has no documented direct economic importance. As a native , it contributes to overall diversity and health. Its presence in an area indicates functioning bee with adequate nesting resources. The has been documented through citizen science platforms (42 iNaturalist observations), contributing to our understanding of bee distribution and . No conservation status has been assigned specifically to this subspecies.

Taxonomic Note

The was described by Theodore Dru Alison Cockerell in 1922. Cockerell was a prolific describer of bees, and his subspecific designations often reflected subtle color variations or geographic isolates. The validity and current recognition of this subspecies may require verification against modern taxonomic revisions of Sphecodes.

Etymology

The subspecific epithet 'ignitus' derives from Latin, meaning 'set on fire' or 'fiery,' presumably referring to distinctive reddish or orange coloration. The 'Fiery Cyclops Blood Bee' combines this with 'Cyclops' (possibly referring to facial structure) and 'Blood Bee' (the standard common name for Sphecodes, referring to their red coloration).
