The control of the dual mating system (both males and females produce pheromone) was investigated using continuous measurements of oxggen consumption.… As the name implies, the Hornet moth or the Hornet Clearwing has an absolute resemblance to a hornet. It was described by Carl Linnaeus in his 1763 Centuria Insectorum. Creatonotos gangis (Linnaeus, 1763) (Fig. By mating preferentially with males endowed with hydroxydanaidal, females may ensure their acquisition of an alkaloidal gift for use in egg defense. Here, we provide biogeographic reconstructions for two widespread pest species in the tiger moth genus Creatonotos (Lepidoptera: Erebidae: Arctiinae) based on the mitochondrial … The Hornet moth is actually a great example of mimicry and that is the sole reason why it makes the top ten list of the weirdest moth species. When males want to start wafting their pheromones around, their coremata are forced out of their abdomens using ‘sclerotised’ levers made from hardened cuticle. Posted by 2 years ago. Creatonotos gangis is a species of moth that lives in Southeast Asia and parts of Australia. Both Creatonotos gangis and C. transiens are typical generalist species, which may inhabit a variety of environments, including agricultural lands and even urban areas (e.g., Delhi) [16,17]. Pyrrolizidine alkaloid sequestration by insects is a strategy to facilitate defense and mating. The moth's unusual tentacles are in fact scent organs, used to produce pheromones in a bid to attract mates. Most of the time it looks like a normal moth with white wings and a red or yellow body. Also found overseas, Common (1990), gives its Australian distribution as north-western Australia, the Northern Territory and in north-eastern Queensland … Creatonotos Gangis Moth (Creatonotos gangis) This creepy freak of nature is another one of Australia’s horrifying moth species.

The fascinating species does display sexual dimorphism, however, but it does so in a highly unusual manner. Populations of widespread pest insects in tropical areas are characterized by a complex evolutionary history, with overlapping natural and human-mediated dispersal events, sudden expansions, and bottlenecks. Creatonotos gangis shows off his coremata This otherwise unremarkable Australian moth is capable of everting four pheromone-releasing organs (coremata)("hair-pencils"), each of which is longer than the moth's abdomen. Coremata are deployed in either of two ways, depending on the nature of the mating system. Relax. Abstract. According to the naturalists the “alien” in the video is actually a Creatonotos Gangis moth. The different morphological types of sensilla on the antennae of both the species are summarized in Table 1 (Fig. Ecdysone and a dietary alkaloid interact in the development of the pheromone gland of a male moth (Creatonotos, Lepidoptera: Arctiidae). Creatonotos gangis. The moth is called Creatonotos gangis, and it lives in parts of Southeast Asia and Australia. Alive males pump up coremata with air intaking through the abdomen. The creatonotos gangis is a species of arctiine moth found in Southeast Asia and Australia. In the rattlebox moth, Utetheisa ornatrix, male mating success depends upon the presence and titer of PAs in his pheromones –. 389-400 Good luck, mate. On antenna of Creatonotos gangis (Linnaeus): Eight types of sensilla are found on antenna. Within the Old World genus Creatonotos, PAs are morphogenic; the size and complexity of the male-pheromone dispersing structures (coremata) are dependent upon the PA concentrations consumed by larvae . The coremata, or “hair-pencils,” are appendages which, in the case of the male Creatonotos gangis, are hidden away underneath its abdomen. Gary Hevel, a researcher with the department of entomology at the Smithsonian's National Museum of Natural History, said the insect is known as Creatonotos gangis.. Hevel said in an email to The Washington Post that the moth in the video appears to be using its scent glands - those strange little tentacles - to attract a mate.. M Wink, D SchneiderFate of plant-derived secondary metabolites in three moth species (Syntomis mogadorensis, Syntomeida epilais, Creatonotos transiens) Journal of Comparative Physiology , B160: (1990), pp. That site states: “Creatonotos is a genus containing about 10 species of moth found in parts of Africa, southeast Asia and Australia. The reproductive biology of the arctiid moths Creatonotos transiens and C. gangis exhibits a novel ontogenetic phenomenon, the morphogenesis of male coremata size being directly controlled by the quantity of hostplant‐derived pyrrolizidine alkaloids ingested by the larvae.
