Batesian mimics that show similar coloration to unpalatable models gain a fitness advantage of reduced predation. Beyond physical similarity, often exhibit behaviour their models, further enhancing protection against predation by mimicking not only the model's appearance but also activity. In butterflies, there is strong correlation between palatability and flight velocity, weak path. Little known about how fly. Here, we explored four butterfly species/morphs: model Pachliopta aristolochiae,...

Abstract This study investigated the effect of fumarate (FUM) and rice bran (RB), alone together, on in vitro rumen fermentation, methanogenesis methanogens. In incubation was performed with six media that were either unsupplemented (control) or supplemented 10% RB, 5 mmol/L FUM, RB + 10 FUM. Methane (CH 4 ) production, dry matter digestibility, CH per digested matter, total short‐chain fatty acid (SCFA) proportion SCFA, acetate : proprionate ratio, production NH 3 ‐N, population density...

Batesian mimics gain protection from predation by their similarity to distasteful models. In butterflies, it has been thought that species and fly slowly in a straight line, but few studies have demonstrated behavioral similarity, no conducted on mimicry Involving intraspecific polymorphism. Here, we compared the wing stroke among various butterflies: palatable non-mimetic Papilio xuthus, unpalatable Pachliopta aristolochiae, polymorphic polytes (cyrus form, females; mimetic females) clarify...

Many territorial species of butterfly are sexually dimorphic in their wing colours, and males such frequently fight each other, probably attracted by the rival's colour.On other hand, male behaviour should be directed to acquiring mates increase fitness, thus sensitive (usually cryptic) female colour.The present experiments aimed determine whether conspicuous colour or cryptic is more attractive two lycaenid species, Chryso zephyrus smaragdinus Neozephyrus japonicus.A pair models was...

The purpose of this study was to investigate the diversity and fluctuation in ciliate protozoan population rumen cattle. DNA extracted from three ruminally cannulated, crossbred cattle a polymerase chain reaction (PCR)-derived clone library constructed, using specific primer set targeting 18S ribosomal RNA genes protozoa. fragments seven selected clones were validated for standard protozoa-specific real-time PCR assay. Furthermore, protozoa methanogens determined by PCR. A total 60...

Abstract Dimorphic female-limited Batesian mimicry in the swallowtail butterfly Papilio polytes is regulated by supergene locus H , harbouring mimetic ( ) and non-mimetic h doublesex dsx gene. In present study, we demonstrated that dsx-H negatively affects number of eggs laid, hatching rate, larval survival adult lifespan. When crossed with hh males, laid females (genotype HH was lower than ). Moreover, Hh fewer when males. The rates were both female male parents harboured . lifespan shorter...

Utilization of wing colors in intraspecific communication butterflies has been widely examined for males, but much less females, and inconsistent results on the female preference male have reported. In present paper, we report examinations virgin females color a sexually dichromatic lycaenid, Pseudozizeeria maha. Females were subjected to choice tests between two models that differed made butterfly wings or butterfly-shaped pieces paper. Models presented with rotating revolving movements...

Courtship behavior was observed for 14 butterfly species, including seven species belonging to tribe Theclini, Lycaenidae, address whether males of sexually dichromatic perform more active demonstration their wing surface the female than those monochromatic do. Males in nearly half kept wings closed on thorax throughout most a courtship, indicating no general relationship between mode coloration and courtship behavior. The results obtained are discussed from ecological phylogenetic points...
