Heng halpuah te hi tute nge ni tak tak?
A hmasa berah chuan sawi tur pawimawh ber chu firefly hi a takah chuan fly chi khat a ni lo tih hi a ni. An hmingah "fly" tih thumal awm mahse, a takah chuan rulhut chi khat an ni. A dik tak chuan beetle chhungkaw `(Lampyridae) zinga mi an ni.` Khawvel pumah heng meikhu chi hrang hrang 2,000 chuang an awm a.

Tichuan thlasik laiin an pupate a, a tawpah chuan kan hmuh thin meialh thlawk (flying fireflies) an lo ni ta a ni.
A awlsam zawngin sawi ila, firefly hi fly a ni lo va, êng siam chhuak thei beetle bik a ni.
Chuti a nih chuan heng meikhu te hian eng nge an ei? Firefly chi thenkhat, a bik takin an larval stage-ah chuan sa ei thin an ni. Chumi awmzia chu ran te tak te, rulhut leh rulhut ang chi te chu an man a, an ei thin tihna a ni.

Mak tak mai chu firefly chi puitling thenkhat chu engmah ei lovin an dam khawchhuak thin !
Engtin nge he taksa te tak te atang hian eng nge a lo chhuah theih ang?
Meipui kan hmuh hian zawhna lian ber kan neih chu, "Engtin nge he thil nung te tak te hian eng a siam chhuah?" Hei hi biological process mak tak a ni. Bioluminescence an ti a.
Firefly te hian an hnuai lamah êng siamtu taksa peng bik an nei a. Heng taksa peng hrang hrangah hian chemical pahnih a awm a.

Mahse, hetah hian "mahse" tlemte a awm. Meikhu hi mihring tan chuan rimchhia ni lo mah se, ei tum ran dangte tan chuan rimchhia a ni thei . Firefly chi thenkhat chuan an taksaah defensive steroid ``lucibufagins`` an tih chu an siam chhuak thin. Hengte hi chemical tha lo tak tak, thlum nuam lo tak nei an ni.
Sakeibaknei, rulhut, rulhut, a nih loh leh meipui pawhin ei tum ta se, he thlum duhawm lo tak hi an hre ngei ang tih han ngaihtuah teh. Poisonous a ni a, an natna a thlen thei hial a ni.
