Mimetism I know a woman who had a tick attached to her arm for 2 3 days before she realized it She was trekking in a difficult spot and didn t change clothes for that long only washing face hands When she reached the camp she finally took a shower and only then she discovered the tick It was cream colored although most ticks we had seen had always been black So we wondered when ticks mature on a host can they take the color of the host s skin or hair coat
