The Palaearctic to Australasian Luciolinae are among the largest subfamilies of fireflies (Lampyridae).
These seem to be all "flashing" (as opposed to "continuous-light") fireflies. Several tropical species, notably of the genus Pteroptyx, are of local economic importance. Their displays will self-synchronize until the entire local firefly population flashes in the same rhythm, creating a stunning spectacle that is popular with tourists. The most well-known location to witness these displays is on the Selangor River at Kampong Kuantan, Malaysia.
Two Japanese species of Luciola, collectively known as hotaru (蛍), are highly significant in Japanese culture and folklore. They are symbols of the hitodama (人魂 or 人玉), the souls of the newly-dead. See also the explanations at the article on the movie Hotaru no Haka ("Grave of the Fireflies") for a discussion of the cultural significance of the hotaru.
[edit] Systematics
This subfamily is usually divided into two tribes, the monotypic Curtosini and the larger Luciolini. Occasionally, the Ototetrinae are contained in this subfamily as a third tribe Ototetrini. The genus Pristolycus, usually placed in the Lampyrinae, might belong in this subfamily instead.
While Curtos certainly stands apart from the other genera, its precise relationships are far less resolvable than the placement as a distinct tribe presumes; it appears to share more autapomorphies with Atyphella and especially Pygoluciola than with other genera, but whether this means an evolutionarily closer relationship (rendering the Curtosini invalid) remains to be tested.[1]
From phylogenetic analyses of morphology, 3 possible clades (which could be considered tribes) can be inferred:[1]
- A basal group containing Bourgeoisia, Hotaria, Lampyroidea, and the "typical" Luciola
- A robustly-supported and distinct group containing Colophotia, Pteroptyx, Pyrophanes, and Luciola species from Australia. They might be distinguished by larvae with soft terga that lack paranota, but this might alternatively be a plesiomorphic trait also present in other Luciolinae.[2]
- A weakly-supported group of Atyphella, Pygoluciola and possibly Curtos, which each seems very distinct but of unclear relationships with the other genera and groups.
