The Strawberry Poison Dart Frog, along the Green and Black Poison Dart Frog, are one of the common diurnal species that can be found in tropical rain forests in Costa Rica, particularly at the Caribbean side. It is common to go hiking and see these bright red and blue frogs suddenly jump from the trail. Due to the color of their legs, they are also called the “Blue Jeans”, although in Costa Rica some individuals are found that have red legs and arms, and in other countries like Panama there are many more morphs with entirely different color patterns. Regardless of the specific colors, they are very conspicuous and do not camouflage well on the leaf litter that tends to be brown to black. They are tiny when compared with many Tree Frogs.
As with the Green and Black Poison Dart Frog, caution must be taken not to touch these frogs when photographing them with macro lenses, as their skin is poisonous and any contact of their secretions with our eyes, nose or mouth can cause much discomfort. While handling them does not produce any symptons, if one is careless, then it is possible to touch one´s sensible organs with the hands and experience significant effects, up to partial blindness.
The Green and Black Poison Dart Frog is one of the species in this family that occurs in Costa Rica, along with the Strawberry Poison Dart Frog and other species, although this species is bigger than the Strawberry. Poison Dart Frogs are diurnal, so it is relatively common to flush them from the floor litter during hiking trips through forested areas. Their contrasting body color is an adaptation meant to signal their poisonous skin to potential predators, helping these frogs escape from danger. Poison Dart Frogs are known because of their ability to withstand ant venom and convert it into their own which means the older the frog, the more poisonous it becomes. Some of these species were used by aboriginal people in South America to kill monkeys and other prey, by rubbing their skin to the arrows that they shoot.
It is normal to see Poison Dart Frogs resting on the leaves of bromeliads, where they usually deposit their larvae, which will develop inside a water pool in the base of a bromeliad leaf. They are more conspicuous when seen on leaf litter, which usually turns brown as the vegetation decays. Also poisonous species like this one are more active during the day. The two times I have had the opportunity to photograph this species, I was careful to keep my distance, as they jumped around quickly and could touch me at any moment. While being touched generally won´t produce any reaction, being careless afterwards and bringing the hands to touch the eyes or the nose after having grabbed one of these can produce significant effects, up to partial blindness.
