Tus npauj Skeptical

Ntawm lub peppermint Pericopinae. Kuv kaw no yees duab nyob rau qaum teb Costa Rica lig ua ob peb xyoos dhau los. Thaum kuv mus txog tos no npauj, yog tsis txhob noticing tus cwj pwm. Tus npauj, Chetone angulosa (Erebidae: Pericopina) ((muaj Arctiidae)), muaj ib qho defensive mechanism ntev – lawv raws hemolymph los deter would-be attackers. Ntau npaub li no, tab sis kuv muaj yeej tsis pom nws li spectacularly dlhau theem teev tseg. Yog tias koj mloog zoo zoo koj yuav hnov lub suab hissing li lub kua pumped cev nqaij daim tawv. Dab tsi yog impressive tshaj yog yuav xav li cas nws hnov ntawm peppermint… xav kom txaus tshuav kuv cia li muab nws tus mus. Sadly, nws tsis saj tsis li advertised. Thaum nws excruciating tsis, cov nyhuv thaum tseem yog ib tug huam loog uas ntawd kub ntev li ib feeb ntau. Khoom zoo nkauj hwj chim, thiab kuv yuav xav txog tej yam pab txhua tus ntxim rau ib tug me noog los yog tsiaj tej zaum yuav tsis txaus luag.

No mas, xws li biologists muaj ib tug cwj pwm funny ntawm tasting lawv compound. Kuv nyuam qhuav zaum saum ib tug hais lus herpetology txog cov qav lom-dart. Rau ib tangent me ntsis, koj puas paub tias cov coloration no famously qav aposematic yeej tsis tau mus kuaj thaum nyuam qhuav? Yog paub zoo tias tus Disease fact tias lawv lom, tab sis tsis muaj leej twg puas tau muab lub sij hawm saib yog cov xim ua tau zoo ib lub qauv tseeb aposematic, uas yog – ua lawv yeej deter txhom tau hauv cov qus? Puv kuj ceeb tias tsis, yog, lawv yeej ua li. Tab sis, nws yog qhov zoo los yeej muaj quantitate tej ntaub ntawv kom them nyiaj yug no assertion held ntev. Rov qab mus tasting – ntsuam herper paub zoo tias yog muab cov qav los qav kaws ib lick. Thaum no yuav ua tau pab qhia tau hais tias hom herp, nws yuav zoo yog ib qho txaus luag sab nyhuv uas teev ntev hauv lub teb. Tsis tau ib herper kuv tsis nco qab lub npe los yog pab pawg neeg no koj yuav; tab sis ntawv nto moo mus ua poj depths lauj cov tastes, hwj chim nyhuv thiab rau tej kev piam sij uas muaj txhua hom kab licked qav kaws (qhov no yog ib legit taxonomic rov).

Cov piv txwv xwb kom pab tau tasting rau hauv kab me me uas kuv yuav xav txog muaj cai tam sim no yog rau ob tug strikingly zoo butterflies- Papilio thoas/cresphontes. Kuv ntseeg tias thoas muaj tus ntxhiab tsw flowery qab thaum koj ntes nws tshiab (yog, ib tug saj tsis… tab sis, nyob), Txawm li cas los kuv yeej tsis tau pom no luam tawm los yog ntsuam xyuas nws kuv tus kheej, ces yuav ua apocryphal. Nws yog butterflies tab sis zoo paub ntau li na xav txog lawv cov hostplant: xws li Speyeria coronis losis pa ntawm Apocynum (zaub tsw muaj zog). Rau ntxiv kev tshawb nrhiav ntawm no ntau ntau. Tab sis tsis muaj ib tug tsis ntseeg ib tug biologist siv tag nrho tsib nws tsis totaub thaum twg nws yuav.
