Unlike Ixodes, Dermacentor ticks cannot mate prior to taking a blood meal. They do cling together pretty tightly. When ticks mate, the male pushes a spermatophore into the genital opening of the female with his mouthparts. With Ixodes ticks, which can mate off the host because males begin developing spermatophores as immatures, males cling to the undersides of females for hours while mating.
