Pretty much any area with a lot of fallen trees/logs should work. Although Capreolus are supposedly not found in fallen logs, it does indicate that the it is still an unmaintained natural area that they do appear in. You can look on iNaturalist to see where other sightings have been.
You should have Lucanus Capreolus and Lucanus Placidus. Capreolus are very common, however you will probably need some form of blacklight/light to attract them, personally I haven't found any without it, but a ton with.
