For birds there are Lithuan names, i did not check the others but this is the international variant, so guess 99% will not even have a Liothuanian name at all.because the species does not occur in Luthian…I stopped checking further as the website transferred fully Lithuanian…
The link is birdgroup 4, butterflies i Guess ? I think 1 will be birs
Wikidata is also an option…for everybody
