Midland painted turtles are a hybrid of the western and southern subspecies
Painted turtles are the most widespread native turtles in North America, ranging from southern Canada to northern Mexico. They are the only species to range across the entire continent. There are four subspecies of painted turtles: the Eastern Painted Turtle (C.p. picta), the Midland Painted Turtle (C.p. marginata), the Southern Painted Turtle (C.p. dorsalis), and the Western Painted Turtle (C.p. bellii). The Midland Painted Turtle is a hybrid of the western and southern subspecies.
The subspecies of painted turtles evolved during the last ice age, around 100,000 to 11,000 years ago. During this time, painted turtles were divided into three populations: eastern painted turtles along the southeastern Atlantic coast, southern painted turtles around the southern Mississippi River, and western painted turtles in the southwestern United States. When the glaciers retreated, the western and southern subspecies met in Missouri and hybridized to produce the midland painted turtle.
The midland painted turtle then moved east and north through the Ohio and Tennessee river basins. It is now abundant throughout much of its range, and most populations appear to be relatively stable. The midland painted turtle is considered a subspecies of the painted turtle (Chrysemys picta), which is the only species in the genus Chrysemys. The parent family for Chrysemys is Emydidae: the pond turtles.
The easiest way to distinguish a Midland Painted Turtle from a Western Painted Turtle is by examining the plastron, or bottom shell. The Midland Painted Turtle's plastron has a symmetrical, dark shadow that is generally smaller than the Western Painted Turtle's. The Midland Painted Turtle's plastron is yellow or dark tan with a darker, irregular "butterfly" marking along the midline. The carapace (upper shell) of the Midland Painted Turtle is olive to black with red or dark orange markings on the marginal scutes (enlarged scales on the shell), as well as red and yellow stripes on the head and neck.
The midland painted turtle is found in Ontario, Canada, and its range extends through the Ohio and Tennessee river basins. It is susceptible to the same threats that have caused the decline of Ontario's other seven turtle species, including loss, degradation, and fragmentation of habitat. Nest predation, particularly by raccoons, foxes, and skunks, is a significant threat to this subspecies.

Eastern painted turtles are found in Quebec, Nova Scotia, and New Brunswick
The painted turtle (Chrysemys picta) is the most widespread native turtle of North America. It has been around for at least 15 million years, with fossils dating back to that time. They are commonly found around quiet bodies of water, such as swamps, marshes, ponds, and bogs, and will quickly move into the water if they feel threatened or disturbed. They can be identified by their dark shell, which has olive lines running across it, and their brightly coloured markings along the head, neck, and shell.
Eastern painted turtles are a subspecies of the painted turtle and, as the name suggests, they are found in the eastern regions of North America. They are easily identifiable by their red markings, with a dark shell that can be olive green to black and may possess a pale stripe down the middle. They have a wide range, from South Carolina up to southern Canada, including Quebec, Nova Scotia, and New Brunswick. In Canada, Eastern Painted Turtles are dormant during the winter months and are typically active from April until early October. They are the most common and colourful turtle found in Nova Scotia, where they are found in a variety of habitats but prefer shallow aquatic habitats with slow-moving water.
In Quebec, the Eastern Painted Turtle may intergrade with the Midland Painted Turtle. The Midland Painted Turtle is found in south-central Ontario and Quebec, and west of the Connecticut River. The two subspecies are closely related and can interbreed, producing offspring known as "intergrades". While Eastern Painted Turtles are found in Quebec, they are not as prevalent there as in other regions.
Eastern Painted Turtles are also found in New Brunswick, where they are one of three painted turtle subspecies found across southern Canada in a non-continuous distribution from British Columbia. They are found in slow-moving, relatively shallow, and well-vegetated wetlands and water bodies. Like in Nova Scotia, Eastern Painted Turtles are the most common turtle species in New Brunswick.
The breeding period for Eastern Painted Turtles is from March to mid-June, with peak breeding time in April. Males perform an elaborate mating ritual, facing the females and waving their long front claws. After breeding, the female will leave the water to dig a nest and deposit her eggs, typically between May and July. The nest is usually within a few yards of water but may be up to half a mile away, and females may travel significant distances to find optimal nesting sites.

Midland painted turtles prefer shallow, slow-moving, well-vegetated wetlands
The painted turtle (Chrysemys picta) is the most widespread native turtle of North America. It has four subspecies in the United States: the eastern painted turtle, the midland painted turtle, the southern painted turtle, and the western painted turtle. The midland painted turtle is a subspecies present in central and southern Ontario, including the Sydenham River Watershed.
The breeding period for painted turtles is from March to mid-June, with peak breeding time in April. Males perform an elaborate mating ritual by facing the females and waving their long front claws. After breeding, the female will leave the water to dig a nest and deposit her eggs. The nest is usually within a few yards of water, but may be up to half a mile away. Females may travel significant distances, crossing roads, to find optimal nesting sites. The female painted turtle is especially vulnerable to being hit by vehicles while crossing roads.
The painted turtle is genetically adapted to survive extended periods of sub-freezing temperatures with blood that can remain supercooled and skin that resists penetration from ice crystals in the surrounding ground. The eastern painted turtle, in particular, can be found in slow-moving water habitats throughout the Chesapeake watershed. They have red coloration on the edge of their carapace and two pairs of bright yellow on their head and neck.

Eastern painted turtles have red markings on their shell and yellow stripes on their head and neck
The painted turtle (Chrysemys picta) is the most widespread native turtle of North America, with a range extending from southern Canada to northern Mexico, and from the Atlantic to the Pacific. They are most commonly found in large wetlands with slow-moving waters and emergent vegetation. The painted turtle is the only species in the genus Chrysemys, which is part of the pond turtle family Emydidae.
There are four subspecies of painted turtles in the United States: the eastern painted turtle (Chrysemys picta picta), the midland painted turtle (Chrysemys picta marginata), the southern painted turtle (C. dorsalis), and the western painted turtle (C. bellii). These subspecies evolved during the last ice age when painted turtles were divided into three different populations: eastern along the southeastern Atlantic coast, southern around the southern Mississippi River, and western in the southwestern United States.
Eastern painted turtles can be easily identified by their distinctive markings. They have red markings on the edge of their carapace (upper shell) and two pairs of bright yellow stripes on their head and neck. The carapace is olive green to black and may possess a pale stripe down the middle. The bottom shell, or plastron, is typically yellow, but can also be stained a rust or red colour. The skin of the eastern painted turtle is dark, ranging from olive to black.
The eastern painted turtle is one of the two subspecies of painted turtles found in Connecticut, the other being the midland painted turtle. While the two subspecies can be distinguished by their markings, they do interbreed in the state, producing offspring known as "intergrades".

Painted turtles are commonly found around quiet bodies of water
The painted turtle is an aquatic species that thrives in shallow, slow-moving fresh waters with soft bottoms, basking sites, and aquatic vegetation. They are often found in wetlands, swamps, marshes, creeks, and the shores of lakes. The eastern painted turtle, for example, is very aquatic and prefers habitats with slow-moving water. They can also be found in brackish waters along the Atlantic coast, from South Carolina to southern Canada.
The painted turtle's preference for quiet waters and specific habitat types varies among the subspecies. The midland and southern painted turtles, for instance, seek out especially quiet waters like shores and coves with dense vegetation. They also have an unusual tolerance for pollution. The western painted turtle, on the other hand, is found in the southwestern United States.
The painted turtle's range and distribution are influenced by their ability to survive freezing temperatures. They are genetically adapted to withstand extended periods of sub-freezing temperatures due to an antifreeze-like substance in their blood. This adaptation allows them to survive winters in their nests, enabling them to extend their range farther north than other American turtles.
The painted turtles' breeding period is from March to mid-June, with peak breeding in April. Males perform elaborate mating rituals, and females lay their eggs in nests near water, typically within a few yards but sometimes up to half a mile away. Unfortunately, female painted turtles are often killed by vehicles while travelling to and from nesting sites, which can fragment their habitats and threaten local populations.
