Chrysoperla plorabunda, also known as the weeping green lacewing, is an insect belonging to the cryptic carnea complex of the genus.

[5] The intensity of color change that occurs in either direction can vary depending on the life stage of the individual, as well as the speed of transition from long to short days.

This is a maintained, motionless posture that involves both behavioral and psychological changes associated with death, and is undertaken when larvae are in close proximity to a predator.

This larval stage typically lasts two to three weeks, with three instars taking place before the final cocoon and adult emergence, which occurs in 10–14 days.

Chyrsoperla plorabunda males and females initiate copulation through identical substrate-borne vibrational mating songs.

[1] The songs consist of volleys produced by low-frequency abdominal vibrations with downward modulation, which are repeated with a regular period.

[15] These faster songs have been shown to ensure that sex recognition can take place quickly, as well as to serve as a determinant of mating success.

[15] In addition to their role in initiating copulation, Chrysoperla mating songs also act as a mechanism of prezygotic behavioral isolation.

[17] This effectively isolates C. plorabunda from any other song morphs, as closely related species occupy adjacent but significantly different acoustic spaces.

[18] Compared to other autosomes, these chromosomes have lower rates of recombination, thus functioning to keep together the loci that are important to song phenotype and preference.

[18] It is likely that there are other loci of small effect related to volley period spread throughout the genome, mutations to which have resulted in the rapid speciation observed in the C. carnea complex.
