Lighting anything reflective without getting burnt out highlights is one of the difficult things you learn to do in studio work. In nature and with natural light we can have a similar issue with shiny animals, wet frogs as above, or Asian beetles, for example.
In the studio you can move the lights and the subject, in nature you can move and the subject and light remains in place.
You can use reflectors (even white cardboard) to block some light (gobo the light in film speak) or diffusers to soften the light. Blocking or diffusing the light often works but can sometimes add artificiality just like a strobe or flash can. Polarizer filters can sometimes help. But these solutions may be cumbersome in the field and scare away your subject.
Here I did what I could to get into a good position but I was not a hundred percent successful; you can see bright burnt out spots on the legs, not enough to distract, just enough to lend realism to the shot. Of course you could remove even those modest points in post-processing but in this case why bother.
I suspect that many amateur nature photographers who deal with this everyday would be surprised how well this skill would help them in a studio!
