FIGURE 4. Biological characteristics of ticks. (A) Female ixodid tick, feeding position (dorsal surface of tick). (B) Feeding aggregation of ixodid ticks, Amblyomma variegatum (the tropical bont tick), on a heifer. (C) Ventral surface of ixodid tick, Amblyomma variegatum showing splayed palps in feeding position. (D) Ventral surface of ixodid tick, Hyalomma anatolicum (no common name) showing teeth on the hypostome. (E) Larvae of Rhipicephalus microplus (cattle tick) questing on grass. (F) Adult female Ixodes ricinus (castor bean tick) questing on grass. (G) Adult female H. anatolicum actively seeking a host. (H) Adults of A. variegatum actively seeking a host. (I) Adults of A. variegatum; fed male, engorged female, and exhausted female after laying the batch of approximately 20,000 eggs. [These species of ticks do not occur in Australia but are nonetheless instructive about the biology of the Australian ticks.].
