I don´t really remember the name of the species that does this!  I am pretty sure it´s a roedent.

Lemmings, but it's a myth. They don't really do that.

They might be a type of millipede. I've heard olf them infesting damp areas. If the curl up into balls when you poke them, they probably are.

I can't quite tell from the pictures, but it looks like they might be the nymphs of boxelder bugs (Boisea trivittatis).  They are harmless bugs that feed on maple trees, but sometimes wander into people's homes in large numbers looking for a place to overwinter.\n\nI have never seen eggs like that for boxelder bugs though.  Boxelder bug eggs are usually a rather scattered spattering of eggs on the underside of a maple leaf somewhere.  So they could be something else, like a milkweed bug, or possibly even a Coreid (which do often lay their eggs in a linear row like that).  Coreids are predatory, and can actually inflict a rather nasty bite if handled (one bite I received from a tiny nymph was actually much more painful than any wasp sting I've ever gotten).\n\nCheck out the True Bugs pages on this site:  http://whatsthatbug.com/ for some images that might give you a better idea of what you have there.

some animals exhibit unusual behaviour around the time of an eclipse.

Unfortunately this is a sign of disease in fish. It usually comes before their death. You could try an antibacterial remedy.

Hi! I believe it's a Compsocerus violaceus. Here in Argentina it is commonly known as "Santa Rita", and it belongs to family Cerambycidae (long-horned, wood boring bugs).\nCheck the photograph at the link just to be sure!

sounds like a warbler...but hard to tell from just this description, and not knowing where you live.  The two that pop into mind with that coloring could possibly be a Yellow-rumped Warbler, or Golden-winged Warbler. (maybe a female)\n\nhttp://www.mbr-pwrc.usgs.gov/id/framlst/i6420id.html\nhttp://www.enature.com/fieldguides/detail.asp?allSpecies=y&searchText=Yellow-rumped+Warbler&curGroupID=1&lgfromWhere=&curPageNum=1

Thatis a terribly vague description, but I am guessing some sort of ichneumon fly.

Oh well, with that information it's easy to identy. \n\nThe  creature is Biplaium kewense. They are commonly known as "worm killers".  See the link below for some photos\n\nAs others have guessed it is a planarian. Worm killers are an exotic pest species imported from Viet Nam in the soil of potted plants. They are carnivorous and hunt earthworms and small insects. They immobilise their prey by coating them with that slime they secrete and then stick a tube into them and suck their insides out.\n\nBTW, well spotted that it uses it's head like a sensor. That is exactly what they do. There are pits under the head that act like a nose that enables the animal to track earthworms, slugs and other prey animals.

After thinking it over, my answer is...DWAIN!  Ha-ha!  That is cute.  Thanks for the clue!

It could be a mole cricket. They kind look like a crab with large pincer like things in the front of the head. They are not harmful, although I have not put my finger in the pincers to find out, but they are a cricket that lives in the ground or pot plants and they use their pincers to cut plants off from their roots. Without seeing it, I can't really tell, but it could be anything, there are millions of different bug species out there. Catch it in a jar and take it to your local agricultural department and get it identified,thats what I did. Good luck.

It would be really difficult to pinpoint exactly what type of creature this is. I would bring it to your local DNR for identification. I live in the UP and actually found something that sounds like you are referring to and the DNR identified it as a sub species of sea lamprey called a brook lamprey. Good luck!!!

...a black widow spider?\nEDIT: Note that you've already asked and chosen an answer for this riddle before.  But for the sake of it, a scorpion.  \nThe mighty one is the sun.  The scorpion is a zodiac, or a "sun-sign".  \nThe female scorpion eats the male scorpion.

Mmm... it could have been an escaped pet. You could try to contact your local faunal control service and let them know, I'm sure environmental agencies would be interested in knowing about any possible exotic species. \nOne popular pet tree frog is Agalychnis callidrias (originally from Central America). Did it look like this?\nhttp://www.froggyville.com/images/graphics/usenet/wild28%5B2%5D.gif

It sounds as though it is most likely the highly luminous Click beetle (Family Elateridae) Pyrophorus noctilucus, as several others have already mentioned.\n\nThis beetle, sometimes also called the Fire Beetle, has two bioluminescent patches on its pronotum, behind the head, that look somewhat like glowing eyes or headlights.  Allegedly they can be bright enough to read by.\n\nPyrophorus noctilucus is native to Central and South America, so it is not outside the realm of possibility that one could show up in South Florida.\n\nInterestingly enough, this critter in giant form is the basis of one of the classic Dungeons & Dragons critters, the Fire Beetle, found in the original Monster Manual.  (OK, maybe that's not that interesting unless you are as geeky as I am).

You might be more successful with your search if you get the scientific names right. ;-)\nThe species is Testudo graeca, and the subspecies are \nT. graeca graeca\nT. graeca ibera\nT. graeca terrestris\nand there are several subspecies, although their validity and status are questioned.\n\nHere's some good information:\nhttp://www.chelonia.org/Articles/Whatisagolden.htm
