Tus txiv neej xaiv ib tsob ntoo, gnaws los ntawm cov tawv ntoo thiab tsim ib lub mating chamber rau hauv uas nws attracts ib tug poj niam los ntawm kev tso pheromones. Ib tug poj niam fertilized tsim 2-3 uterine kab, uas nws lays nws qe. Cov larvae tshwm sim ua cov kab lus sib npaug mus rau axis ntawm tsob ntoo, ntawm lawv qhov kawg muaj cov menyuam txaj
Cov poj niam nyob rau yav qab teb cheeb tsam, 3 lub lis piam tom qab lub davhlau tseem ceeb, nteg lawv cov qe dua, thiab ib tug muam tiam tshwm sim los ntawm lawv. Nyob rau sab qaum teb, hom kab kab no tsuas muaj ib tiam ib xyoos xwb. Tab sis cov nuj nqis no yuav txawv nyob ntawm qhov ntsuas kub.
Cov kab me me pub rau bast thiab ua ntxiv txav kom tawm mus. Puberty ntawm beetles kav 2-3 lub lis piam, thiab nyob ntawm qhov kub thiab txias tswj.
