מאָל פּערפיום דורך קריס גרינטער, אויף מאי 4, 2010 פון אַ פעפערמינץ פּעריקאָפּינאַע. איך רעקאָרדירט דעם ווידעא אויף-פּלאַץ אין צאָפנדיק קאָסטאַ ריקאַ אַ ביסל יאָרן צוריק. ווען איך ריטשט אַראָפּ צו קלייַבן אַרויף דעם מאָל, עס איז שווער צו ויסמייַדן נאָוטיסינג די ופפיר. די מאָל, טשעטאָנע אַנגולאָסאַ (נאָקטוידאַע: פּעריקאָפּינאַע) ((געניצט צו זייַן אַרקטיידאַע)), האט אַ פּראָסט דיפענסיוו מעקאַניזאַם פֿאַר דעם גרופּע – they excrete hemolymph to deter would-be attackers. Lots of moths do this, but I have never seen it so spectacularly displayed. If you listen carefully you can hear the hissing sound as the fluid is pumped form the body. What was most impressive is how strongly it smelled of peppermint… strongly enough that I just had to give it a go. סאַדלי, it didn’t taste as advertised. While it wasn’t excruciating, the most noticeable effect was an abrupt numbness that lasted for a several minutes. Pretty potent stuff, and I can imagine the effect on a small bird or mammal might be far less amusing. It seems like biologists have a funny habit of tasting their subjects. I recently sat in on a herpetology talk regarding poison-dart frogs. On a slight tangent, did you know that the coloration of these famously aposematic frogs has NEVER been tested until recently? The fact that they were poisonous is well known, but no one ever took the time to see if their colors actually fit a true aposematic model, that is – do they really deter predators in the wild? Turns out not surprisingly, יאָ, they do. But it’s nice to actually have quantitate data to support this long held assertion. Back to tasting – a well known herper test is to give the frog or toad a lick. While this can actually help to identify the species of herp, it more likely seems to be an amusing side effect of long hours in the field. Not being a herper I can’t recall the name or group this applied to; but a famous paper went into great depths to describe the tastes, potent effect and the potential dangers associated with each licked toad species (this was a legit taxonomic review). The only example for useful tasting in insects that I can think of right now is for two strikingly similar butterflies- Papilio thoas/cresphontes. I believe thoas has a sweet flowery smell when you catch it fresh (יאָ, not a taste… but close), however I’ve never seen this published or tested it myself, so it may be apocryphal. It is however well known that many butterflies smell strongly of their hostplant: such as Speyeria coronis smelling of Apocynum (strong vegetable odor). Lots of room for further investigation here. But without a doubt a biologist uses all five of his senses whenever he can.

Chumhrán Leamhan Ag Chris Grinter, 4 Bealtaine, 2010 Ó phiobair Pericopinae. Thaifeadadh mé an físeán seo ar an láthair i dtuaisceart na Costa Rica cúpla bliain ó shin. Nuair a shroich mé síos a phiocadh suas an moth, bhí sé deacair a sheachaint noticing an iompar. An moth, Chetone angulosa (Noctuidae: Pericopinae) ((úsáidtear a bheith Arctiidae)), Tá meicníocht cosanta coiteann don ghrúpa – excrete siad hemolymph a dhíspreagadh mbeadh-a attackers. Go leor de na leamhain é seo a dhéanamh, ach ní fhaca mé é sin ar taispeáint mórthaibhseach. Má tá tú ag éisteacht go cúramach is féidir leat éisteacht leis an fuaim hissing mar go bhfuil an sreabhach pumped fhoirm an gcomhlacht. Cad é is suntasaí é an chaoi go láidir smelled sé de lus an phiobair… láidir go leor go raibh mé díreach tar éis a thabhairt dó dul. Faraor, ní raibh sé blas mar atá fógraithe. Cé nach raibh sé excruciating, Ba é an éifeacht is suntasaí ar numbness tobann a mhair ar feadh nóiméad roinnt. Stuif Pretty potent, agus is féidir liom a shamhlú an éifeacht ar éan beag nó a d'fhéadfadh a bheith i bhfad níos lú mamach amusing. Dealraíonn sé cosúil go bhfuil bitheolaithe nós greannmhar blaiseadh a n-ábhar. Shuigh mé ar na mallaibh i ar caint herpetology maidir le froganna nimhe-DART. Ar tadhlaí beag, raibh a fhios agat go bhfuil an coloration na froganna famously aposematic tástáil déanta riamh go dtí le déanaí? Is é an bhfíric go raibh siad nimhiúil go maith ar a dtugtar, ach gan aon duine a ghlac riamh an t-am chun a fháil amach a n-dathanna oiriúnach i ndáiríre samhail fíor aposematic, is é sin – dhéanann siad a dhíspreagadh ndáiríre creachadóirí sa fiáin? Casadh amach nach ionadh, yes, a dhéanann siad. Ach tá sé deas go i ndáiríre tá na sonraí quantitate chun tacú leis an dearbhú fada ar siúl. Ar ais go blaiseadh – is tástáil herper maith ar a dtugtar a thabhairt ar an frog nó buaf lick. Cé gur féidir leis seo cabhrú i ndáiríre chun speiceas herp a aithint, is cosúil níos mó seans a bheith ina éifeacht taobh amusing uaireanta fada i réimse. Gan a bheith ina herper Ní féidir liom a thabhairt chun cuimhne an t-ainm nó an grúpa seo i bhfeidhm ar; ach páipéar cáiliúil chuaigh isteach doimhneacht iontach chun cur síos a dhéanamh ar an cách, éifeacht potent agus na contúirtí féideartha a bhaineann le gach speiceas buaf ligh (bhí sé seo athbhreithniú tacsanomaíoch legit). Is é an sampla ach amháin le haghaidh blaiseadh úsáideach i feithidí gur féidir liom smaoineamh ar ceart anois ar feadh dhá féileacáin cosúil strikingly- Thoas Papilio/cresphontes. Creidim thoas Tá boladh milis flowery nuair a ghabháil tú é úr (yes, Ní blas… ach gar), áfach, tá mé riamh le feiceáil seo fhoilsiú nó a thástáil féin é, mar sin d'fhéadfadh sé a bheith apocryphal. Tá sé, áfach, ar eolas go maith go bhfuil boladh mhaith féileacáin go láidir ar a n-hostplant: nós Speyeria coronis smelling de Apocynum (boladh glasraí láidir). Go leor de spás le haghaidh tuilleadh imscrúdaithe anseo. Ach gan amhras úsáideann bitheolaí gach cúig de chuid céadfaí aon uair is féidir leis a. Cosúil le seo: Cosúil Ag luchtú ...
