NORMAL TICK BITE PICTURES SKIN
Once embedded in the skin, tick saliva creates a pool of lysed tissue and capillaries below the skin surface, allowing a constant supply of liquid nutrients.
Ticks can even appear a bluish-grey if they have taken a large blood meal.ĭuring the feeding process, ticks cut the surface of the skin with their mouthparts, insert a feeding tube and secrete saliva containing anaesthetic properties so the host cannot feel the tick has attached itself. Unlike mosquitoes which feed for a matter of seconds, hard ticks can remain attached for several days. Their colours also vary from shades of brown and reddish brown, to grey and black. Ticks range in size from smaller than a pin head (larva) to as large as a marble (engorged adult). Adult males feed very little on blood and tend to seek a host in order to find a female tick. Adult female ticks require a blood meal to produce eggs. Larvae and nymphs require a blood meal to grow and moult from one stage to the next. The cycle is then repeated, with the adult tick reaching maturation on its third host. Larvae will then attach to a host and feed over several days, before dropping off to moult to the nymph stage. Larval ticks hatch and can survive for weeks without a bloodmeal. Once engorged, the female will drop from the host and lay a clutch of eggs. Ornate kangaroo tick ( Amblyomma triguttatum)Īll female ticks need to take a blood meal before producing eggs. It can take up to three years for a tick to complete its life cycle, but many die in process, seeking a host. Life cycleĪ tick life cycle generally involves four stages: egg, larva, nymph and adult. This coincides with the spring, summer and autumn months, when the weather is warmer. Peak tick season in WA runs from September to April. They can also actively move toward a host, so care should be taken when resting in open natural environments, including nature reserves, designated clearings and camp grounds. Ticks are found throughout WA in bushland or long, grassy environments where they may climb up blades of grass or vegetation and wait for a host (animal or person) to pass by.
