Propylea dissecta
species of insect
Propylea dissecta is a species of lady beetle native to India, Sri Lanka, Bangladesh and Nepal.
Description
This robust beetle is about 5 to 6 mm in length. Elytra reddish orange in color with black central line. Adults show polymorphism with several intermediate and pale forms.
Biology
Sexual maturity of male and female ladybirds is about 7 and 9 days respectively. Adult males are more willing to mate with females irrespective of age. Mating duration is longest amongst older adults where 30 day-old males and 20 day-old females can be found. Chemical signals as well as visual and tactile cues initiate male attraction toward females. Mating lasted longest about 275 minutes when it occurred between unmated individuals.
It is a voracious predator on several aphids such as Aphis gossypii, Aphis craccivora, Lipaphis erysimi, Uroleucon compositae, Brevicoryne brassicae, Rhopalosiphum maidis and Myzus persicae.
This brief starts where responsible research should: with the source description of “Propylea dissecta” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q108466151. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
