When the weather turns warm and sunny, it is not uncommon for me to spot Common Five-lined Skinks (Plestiodon fasciatus), one of the few lizards that are present in my area. Most of the time I see them on the trunks of trees or on fallen logs, but occasionally I will see one on a man-made structure that has crevices and overhangs where they can hide.

Skinks are skittish and will scamper away if they detect my presence, so I have to be super stealthy in approaching them to get a shot. In the case of these photos, I was at the edge of a small pond at Jackson Miles Abbott Wetland Refuge last week looking for dragonflies when some movement on a nearby concrete fishing platform caught my eye. The skink had just crawled out of the shadows and was surveying the area when I captured these images.

Juvenile skinks have blue tails and there appears to be some blue on the tail that is especially visible in the second photo, so I am guessing that it is almost a full-grown adult. Some scientists believe that the blue color functions as a decoy, diverting the attention of predators to this “expendable part” of the body—the tail is detachable and regrows if it is lost. Other scientists propose that the blue coloration serves to inhibit attacks by aggressive adult males, who might otherwise view the juveniles as rivals.

If you are curious and would like to see a photo of the blue tail of a juvenile skink, check out this 2021 blog posting entitled Juvenile Skink in April.
