Akidunga

Kwangua mwiba wa nyuki na upoze mahali hapo.
Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura na umtumie kalamu yake ya adrenalini kama anayo.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

Both sexes squeak to warn predators. Velvet ants rub their abdominal segments together, while crickets rub their legs against their abdomen.1

North American velvet ant species form one of the most intricate mimicry rings in the natural world, split into eight separate rings of mimicry.1

Males find females by smelling pheromones and by following their squeaking sounds. They carry the female in their jaws to a shaded, safe spot to mate.1

Females are wingless, a feature shared by all females in the family Mutillidae.1

Females are believed to mate only once in their lifetime.1

Kuvunja dhana potofu
