Which reptile is identified as an important host for immature *I. pacificus* stages specifically in California?
Answer
The Western Fence Lizard (*Sceloporus occidentalis*)
The life cycle flexibility of *Ixodes pacificus* allows its immature stages—larvae and nymphs—to utilize a diverse range of vertebrate hosts, which contributes significantly to the tick's persistence in varied environments. While larvae and nymphs commonly feed on rodents and birds, the text specifically names lizards as important hosts for these immature stages within California. The Western Fence Lizard, designated scientifically as *Sceloporus occidentalis*, is highlighted as a crucial component of the transmission cycle in that geographical region, supporting the development of nymphs before they seek larger hosts as adults.
