Dinastes tityus lives in the eastern United States, mainly in the Appalachian Mountains, the northernmost point in Illinois, and the southernmost point in Florida. In Mexico and Arizona, D. granti is replaced, and to the south - D. hyllus (almost all of Central America), but all three species do not enter the islands!
D. hercules on the islands lives only in the Lesser Antilles, where it gives several subspecies.

But a certain gentleman who had seen large squashed beetles in Havana and Varadero made just such an assumption. Although I have been to Cuba three times, but so far only during the dry period. In November 2011, I came across a very large maggot right on the hotel grounds. At that time, I was surprised, took a picture and that's it... But somehow in the search engine on the topic ,,Beetle Hercules,, flashed a few photos with beetles and larvae. The larvae looked suspiciously similar to the one I saw on Liberty Island! But Googling about the area, I didn't dig up anything, but only got even more confused. So I turned to the specialists. And 80 kilometers from Florida to Cuba can be an obstacle to the natural settlement of such beetles. There is also a person's help, random or not?!

Strange, but how did the Hercules larva end up near the hotel in the first place? This is not a caterpillar actively crawling on the surface of plants or soil. It lives in the thickness of the compost and quickly dies outside it. And under what circumstances did you find her? Maybe it's just a caterpillar? We can't figure it out without a photo at all. As for Titiis in Cuba, it was also necessary to take pictures. If it had been brought to Cuba, it would have appeared in the articles as an introduction long ago. By the way, in Florida, this species lives in the north.

Scolopendra was looking for it, turning over the leaf litter under a huge tree with a dried palm leaf stalk (one specialist or not I don't know called it Kokoloba). I did this every previous trip, scolopendra always caught it, but I saw this larva (similar in my opinion, to the larva of the Hercules beetle or another Dynastesa) for the first time on the third trip. Indeed, hurricanes are quite frequent there, almost every fall. If after some hurricanes, iguanas appeared on some Caribbean Islands, then beetles could even settle there in this way. And the one-sided attitude of the Pindos to everything Socialist also does not give full confidence about the boundaries of certain areas.

Yes, the hurricanes there are terrible and they have been passing for thousands of years, but the ranges of many species are very stable for some reason. Then this bug would have drifted away long ago. Rather, it's something else. In Titiis, the larva is not very large, since the limits on the size of the imago are 70-75mm, and then these are the rarest individuals, but 55mm is just right. How many cm is your larva approximately in length and how thick is it?

Well, the accuracy of areas, no one has ever tracked very carefully, and their changes over time, too. And the example with iguanas does not say anything, yes, there have always been hurricanes, but on some islands there were no iguanas until recently, but in recent years they have begun to appear. Well, about the size of the larva (as a non-entomologist), in addition to saying that it was large, I can't explain much. And when I saw a photo of the larvae of Hercules, I assumed that it was very similar. And not only I, but also the gentleman who saw large beetles crushed in Cuba, also assumed that they were of the genus Dynastes. As soon as I can post a photo, I will give you a link, and I hope you will help to establish the truth.

Generally meaningless conversation without a photo. You can easily put it in any social network like Odnoklassniki and give a link.
As for the lack of accuracy of ideas about ranges, when it comes to the transfer of the range from the island to the mainland or to the island, this is a rare phenomenon for large beetles. There are practically no recent examples of Dinatin in the New World. But there are plenty of examples of lizards, they often live on the coasts and easily wander on plant debris along the currents.

In my opinion, he clearly explained, the photo is still only on a flash drive, there is no way to put it anywhere yet, as soon as I can do it, I will immediately give you a link. If I had posted it somewhere, I would have given you a link at the very beginning of this topic.
