| 説明 | Ticks may be one of the least pleasant signs that spring is officially here. Fortunately, they are a nuisance that wanes as the spring rolls into summer and the temperatures heat up. Ticks are an external parasite that attempt to grab onto a host that wanders near. They can be found, like this one, sitting atop a blade of grass or other plant, waving their front legs, ready to grab onto the next passerby. This is called "questing". If a tick succeeds in finding a host, it finds a suitable spot, latches on and fills with blood. The tick then drops off and either completes its next life stage, or, if it is an adult female, lays eggs. Photo Credit: Krista Lundgren/USFWS |
