The Cattle Tick (Margaropus annulatus).—The cattle tick, as already mentioned, has received probably more atten- tion than any other species, as it has been known for many years as the carrier of Texas fever in cattle, and its great importance to the cattle industry has been the occasion for elaborate studies regarding its habits.

Once located they retain their attachment until mature. The females when mature and gorged with eggs loosen their hold, drop to the ground and eggs may be distributed wherever the adults fall.
