Tick larvae have six legs, and nymphs and adults have eight legs. (dvm360.com)
Thus, the nymphs typically have ample time to feed and transmit the infection (ticks are most likely to transmit infection after approximately 2 or more days of feeding). (cdc.gov)
Adult ticks can transmit the disease, but since they are larger and more likely to be removed from a person's body within a few hours, they are less likely than the nymphs to have sufficient time to transmit the infection. (cdc.gov)
