Yog li ntawd, yuav ua li cas kom tshem tau cov nyom daj?
Yuav Ua Li Cas Tua Eastern Lubber Grassshoppers
- Xaiv cov nyom nyom los ntawm koj cov nroj tsuag, ntoo thiab paj. Submerge lawv nyob rau hauv ib tug sib tov ntawm 25 feem pua zaub mov detergent tov nrog 75 feem pua dej kom poob lawv.
- Mow koj nyom. Eastern lubber grasshoppers nyiam nyob hauv cov nyom siab.
- Yuav tshuaj tua kab.
- Siv cov tshuaj tua kab ncaj qha rau cov nyom nyom.
Tsis tas li ntawd, lubber grasshoppers puas lom? Sab hnub tuaj Lubber Grasshopper Lawv yog aposematic cov nyom yog heev lom . Lawv yuav tsis tua tib neeg tab sis lawv tua tau ib tug noog me los yog tsiaj txhu.
Ua raws li qhov kev pom no, dab tsi yog lub roj hmab nyom?
Lubber grasshoppers yog ib qho loj tshaj plaws cov nyom , yog li lawv tuaj yeem pom tau yooj yim thaum taug kev ntawm txoj kev hauv Everglades. Lawv kuj tseem qeeb qeeb, uas tseem ua rau nws yooj yim rau koj kom pom qhov pom ntawm lawv. Lawv tuaj yeem loj hlob mus txog plaub ntiv tes. Hom no nyav yog ci ntsa iab xim thiab qauv.
Puas yog cov kab dub thiab txiv kab ntxwv muaj tshuaj lom?
Lub ci xim thiab qauv ntawm lub plhaub lub plhaub yog ib qho aposematic, los yog ceeb toom, qauv rau cov tsiaj txhu uas lawv tsis tuaj yeem ua rau sab xis. lom . Lubbers ingest thiab assimilate tshuaj nyob rau hauv cov nroj tsuag lawv noj uas, txawm hais tias tsis muaj teeb meem rau tib neeg thiab lub lubricants lawv tus kheej, yog lom rau ntau predators.
