Description:This photograph depicted a dorsal view of a male "lone star tick", Amblyomma americanum.
The large chitinous scutum on the tick’s dorsal abdomen identified this as a male of the species, whereas, in the female tick, the scutum is considerably reduced, thereby, allowing for abdominal enlargement when it becomes engorged during ingestion of a blood meal. Also, note the four pairs of jointed legs, placing ticks in the Phylum Arthropoda, and the Class Arachnida.
