Missouri has a number of snakes species, and I've yet to find them all. Here are some of the species I found that are not discussed in other pages on this site and notes regarding them. 

Miksnakes are beautiful and are widespread in Missouri. Grassy openings and the edges of forested areas, as well as large open glades, are good places to search for them. They typically stay hidden under rocks, boards, and pieces of tin during the day.

Eastern Hognose snakes are widespread in the state, but they are not particularly easy to find. They turn up sometimes, but it is difficult to predict when and where they will be seen. They can be found on the crawl or under rocks.

Garter and ribbon snakes can be very attractive snakes. The best looking of the garter snakes in the state have significant amounts of red on them. The ribbon snakes seem to be less common than garter snakes, but both are wide ranging

Wormsnakes and earthsnakes are both widespread and common snakes to encounter under rocks and boards. The wormsnakes are strikingly colored. These species seem more tolerant of shade than many other snakes species.

eThe first picture is a flat head snake. I have not found this species to be very common in Missouri in compared to say wormsnakes or earthsnakes. This one was found in a rocky glade at the edge of some woods. Line snakes can be very common where they are found, but I have also found this species to be of a more localized distribution. Finally, the redbellied snake, I have found this species at multiple locations so it not rare but I have not found them in large numbers and consider them to be a good find.

The plain or yellow bellied watersnake can sometimes indeed have a colorful underside

The most widespread and common watersnake in Missouri is the Northern Watersnake

The first snake pictured is the broadbanded watersnake which is limited to the Southern part of the state. The Graham's crayfish snake is a more secretive species as it does not often come out and bask during daylight like many other aquatic snakes. The one pictured here was found under a partially submerged piece of wood. The diamondback watersnake can get quite large. 

Racers are widespread and common in the state. They seem to prefer open areas or weedy openings between wooded areas. They are often found under cover but can also be very active during the day.

The blackratsnake is a common and widespread species. I have found them in trees in wooded areas, hiding in logs, crossing roads, and under cover objects in open weedy fields. The foxsnake has a more restricted distribution in the state. The ones I have found were in an area that contains a mixture of open agricultural and weedy areas and water canals, with smaller amounts of forested areas.
