Ants in Lefleur's Bluff State Park, Pike County, Mississippi [MS State Park Ants]

Lefleur's Bluff State Park is located on the Pearl river just off of Lakeland Drive in Jackson, Hinds County, Mississippi. There are two entrances to the park, one of which leads to the Natural Science Museum and Children's Museum, and the other that leads to the camping and lake area. The 305 acre park offers camping, fishing, picnic areas, hiking trails, and a golf course. Because the park is situated on the Pearl River, much of the wooded habitat is bottomland hardwood forest, but upland forest ridges are present, and open grassy, park-like areas are found in the campground areas and near the Museums.

I arrived at the park at about 11 AM on Wednesday, 20 July 2011. I had limited time, as I was actually headed to Lake Lincoln State Park and Percy Quin State Park, but this was on the way, so I figured I might as well collect some here. I decided to go to the section of the park where the Nature Science Museum is located so I could talk to Tom Mann, who studies various sandhill animals including gophper tortoises and harvester ants. I had not previously met Tom, and enjoyed his exuberant ramblings about the harvester ants! Also, he is a fellow runner, and we talked about running a bit. After 30 minutes or so, I went outside to collect a few ants.

I first roamed around the open area near the building to see what common ants I could see (32°14'29"N 90°09'27"W). Of course, the ubiquitious imported red fire ants were abundant. Workers of the exotic dark rover ant, Brachymyrmex patagonicus, were also numerous. I collected the black carpenter ant, Camponotus pennsylvanus, as large workers scurried about on trees. Acrobat ants, Crematogaster ashmeadi were also present on trees, and minute thief ants, Solenopsis carolinensis were collected at the base of a tree.

After a few minutes, I headed down the trail behind the museum (32°14'28"N 90°09'18"W). The trail wound through an upland forest with some large trees, then descended rather abruptly to bottomland forest habitat. I collected three gallon sized bags of soil and leaf litter for later Berlese extraction. I collected both Aphaenogaster and Formica (sexuals were present in the Formica nests) colonies that were nesting in rotting logs.

Around 2 PM, I made my way back to the car and headed to Lake Lincoln State Park. I plan on collecting at the campground area of Lefleur's Bluff State Park at a later date.

Overall, I collected 22 species of ants at the park including five exotic species: Brachymyrmex patagonicus, Hypoponera opaciceps, S. invicta x richteri and S. membranifera , and Strumigenys silvestrii, all of which are quite common throughout Mississippi now. For a complete list of the ants collected, see the list below.
