Becquartina bicolor cicada

Sarkar and colleagues named Becquartina bicolor in 2024. It is a cicada in Cicadidae, not a butterfly. [1]

The 2025 phylogenetic study places Becquartina in Leptopsaltriini. [2]

A species name identifies a biological hypothesis supported by comparative evidence. It does not require every individual to have the same colours.

Dark brown forewings bear two contrasting bands and three apical spots; red veins accompany a dark brown-to-black body. Hindwings combine pale basal areas with dark outer fields and pale spots. [1]

Compare the boundaries of each band, its relationship to veins, and the sequence of spots. A broad impression of orange or white is less informative than the arrangement.

The original study records Balpakram in South Garo Hills and Nongkhrah community forest in Ri Bhoi, with humid, shaded forest and tall trees. [1]

Two separated records establish presence at those sites. They should not be drawn as a continuous range polygon without intervening observations.

Cicadas develop through egg, underground nymph and adult stages. Females insert eggs into plant stems; hatchlings enter the soil, and the final moult produces the winged adult. [3]

For this species, adult field observations span April to June. [1]

The adult calendar describes when people encountered the insect. It does not measure how many years an individual spent below ground.

Cicada mouthparts pierce plants and draw sap; nymphs feed from roots. This is the family-level feeding framework. [3]

A precise host record should identify the plant and the observed feeding stage. A perch photograph alone cannot establish a root host.

Males were detected by their calls. Garo Hills calling intensified in mornings and evenings; Ri Bhoi observations showed a different daytime pattern. [1]

Local timing matters when planning a survey. Recording location, weather and time with a call makes it possible to compare observations rather than treating one schedule as universal.

Both sexes occur in both colour forms. The authors treat the forms as infrasubspecific variation, not separate species or subspecies. [1]

The useful distinction is between variation in colour and evidence of a separate lineage. Sorting photographs into two palettes would not justify two taxonomic entries.

Cicadas connect plant sap to predators including birds, spiders and other insects. These are general cicada relationships, not a measured predator list for B. bicolor. [3]

The forest setting invites surveys across soil and canopy together. Adult sightings alone give an incomplete picture of the habitat supporting an underground juvenile.

The name refers to the two colour forms. [1]

The publication date records scientific description, not the origin of the species. Earlier field observations and preserved type specimens provide the evidence behind the name.

A useful conservation record preserves locality, date, habitat condition and identification evidence. Repeated observations at the known sites could reveal changes in adult activity or occupied habitat.

A first description and a restricted set of records do not by themselves establish a formal threat category or a population trend.

In cicadas, a stout body, broad head, small bristle-like antennae and two wing pairs distinguish their anatomy from butterflies. [3]

An upper view and an underside answer different questions. Surface, sex, locality and specimen identifier should stay attached to an image during comparison.

Follow the dark ground, band shapes and apical spots as a linked pattern. Keep the saffron and white forms labelled as variation within the same species, and distinguish observed anatomy from stylistic simplification.

For a physical specimen, keep the original locality and determination labels with it, protect it from direct sunlight and moisture, and minimise handling. A beautiful object loses scientific value when its records are separated.

Which plants support nymphs? Do surveys find the species between its documented localities? How stable are local calling schedules? These questions would connect the known adult pattern with the less visible juvenile and geographic story.

The 2024 description anchors species identity and colour variation. The 2025 study supplies higher classification; the Australian Museum supplies explicitly broader cicada context. Each claim above retains the appropriate scale rather than borrowing an unrelated species' life history.
