Phanogomphus cavillaris, the sandhill clubtail, is a species of clubtail dragonfly endemic to the Southeastern United States, found from Central Peninsular Florida to Southern Alabama as well as some of North Carolina. [1] Adult individuals are found in scrub-like or other dry, sandy, lightly vegetated habitats located near a stream or lake. [1] Just like most other gomphids, the sandhill clubtail has an enlarged end of the abdomen as well as eyes located farther apart than the average Anisoptera.

Description and identification

Overall, the sandhill clubtail has a very similar coloration to most other phanogomphids, a combination of yellow and dark patterning. The general patterning, as well as habitat preference, is nearly identical to the cypress clubtail (P. minutus). P. cavillaris has a straight occiput line (the line in between the eyes near the back of the head) and a dark band across the face, whereas P. minutus has a slightly curved occiput line that is lobed on the sides and an entirely pale yellowish face. [1] While there are other morphological and microanatomical differences between the two, the shape of the occiput line is most useful in the field. [1]

Subspecies

There are two subspecies of sandhill clubtail, both of which are found in Southeastern North America.

The chicken turtle is a turtle native to the southeastern United States. It is the only extant member of the genus Deirochelys and is a member of the freshwater marsh turtle family Emydidae. The chicken turtle's scientific name refers to its extremely long neck and distinctive net-like pattern on its upper shell. There are three regionally distinct subspecies, which are thought to have evolved when populations became separated during periods of glaciation. These subspecies can be distinguished by their appearance; the western chicken turtle displays dark markings along the seams of its plastron, while the plastron of the Florida subspecies is a bright yellow or orange color. Fossil records show that the chicken turtle has been present in the region for up to five million years.

The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, Australia, and Africa. The name refers to the club-like widening of the end of the abdomen. However, this club is usually less pronounced in females and is entirely absent in some species.

<span class="mw-page-title-main">Halloween darter</span> Species of fish

The Halloween darter is a small freshwater fish native to North America. It is found in Georgia and Alabama in the drainage basin of the Apalachicola River, specifically in the Flint River system and the Chattahoochee River system. It prefers shallow, fast-flowing areas with gravel bottoms in small and medium-sized rivers. It was first described in 2008, having not previously been distinguished from the Blackbanded darter (P. nigrofasciata), formerly thought to occur in the same watershed. Blackbanded darter has since been split again with Westfall's darter now recognised from the Apalachicola drainage. The species is somewhat variable, being generally blackish dorsally, with some individuals having indistinct saddle-like barring. Males have orange and dark lateral striping while females have dark stripes and a yellowish-green belly. At a maximum standard length of 101 mm (4 in), males are slightly larger than females, and both sexes develop distinctive orange barring on the edge of the first dorsal fin during the breeding season.

Brachyopa daeckei, the black-tailed sapeater, is a rare species of syrphid fly that has been observed in northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.daeckei larvae have not been described.
