在2008年和2009年8月，观察成年墨西哥湾沿岸蜱，斑点钝眼蜱，在戈蒂埃，杰克逊县，密西西比，美国附近的阴谋的探索高度，行为和空间分布蜱不均匀分布在情节中，被发现主要是在鱼雷草和/或线草沿着，并在一个小的泥土场路。肉眼观察到成年蜱在三种不同的植物上寻找：鱼雷草、白黍、线草、Aristida stricta和约翰逊草、Sorbellhalepense，除了最后一种之外，所有这些植物都有小直径的茎和薄而尖的叶子。蜱虫位于植物的尖端处或附近（双尾二项式概率，p = 0.0074）。观察到的求索高度范围为20-75厘米，平均为36厘米。9/15只蜱虫（60%）观察到探索是头朝上，而6只（40%）是头朝下。使用从田间道路收集的蜱虫，在研究中心进行了有限的标记-释放-再捕获观察。27蜱标记和释放，15个被重新捕获的三个样本跨越24天的时间。其中，5人移近了他们最初被抓获的土路，2人移远了。
During August of 2008 and 2009, observations were made on the questing heights, behaviors, and spatial distribution of adult Gulf Coast ticks, Amblyomma maculatum, in a plot near Gautier, Jackson County, Mississippi, U.S.A. Ticks were not evenly distributed in the plot, being found mostly on torpedograss and/or wiregrass along and in a small dirt field road. Adult ticks were visually observed questing on three different plants: torpedograss, Panicum repens, wiregrass, Aristida stricta, and Johnsongrass, Sorghum halepense, all but the last of which have small-diameter stems and thin, pointed leaves. Ticks were located at or near the tips of the plants (2-tail binomial probability, p = 0.0074). Observed questing heights ranged from 20-75 cm, with an average of 36 cm. Nine of 15 ticks (60%) seen questing were oriented head upward, while 6(40%) were head-down. Limited mark-release-recapture observations were made in the study site, using ticks collected from the field road. Of 27 ticks marked and released, 15 were recaptured in three samples spanning a 24-d period. Of these, 5 had moved closer to the dirt road where they were originally captured and 2 farther away.
