This is one big chunk of amber. It is about 3.5 x 3.5 x .5 inches and weighs 98.2 grams. Inside is a zoo. there is so much inside that I cannot even photograph all of it (and I did photograph as lot.) The most obvious thing is an actual leaf from the tree that produced the resin in the first place. In addition to that, there are numerous worker ants, gnats, midges, winged termites, caddisfly, I even saw an adult planthopper. This is a giant piece of clear Dominican amber. A very impressive piece.
This is a fun one. First, it is NOT Dominican, but it is Mexican amber from Chiapas. Second, this is an interesting piece. Some debris inside along with a large worker termite, Isoptera. Now the cool bit: it has a large bubble inside. This is often called an en-hydro. It is a bubble that you can see move when the amber is tipped. I look at that, know there is water inside the termite's body and wonder. Any bacteria in the water? Any viruses? What would happen if you accidentally broken open the piece and released the water? Here is a very recent article about ancient viruses and bacteria. Is there a bug that would wipe out human kind? Just fun stuff to think about. Here is a good one - a video of the bubble moving, take a look.
Here is a rare one: this is the larvae of an owlfly (similar to an ant lion), Neuroptera, Asclaphidae. They are as rare as hen's teeth. The larvae inject their victims with poison, which serves to paralyze the prey while the owlfly begins feeding. Also in this piece is an ant, and a mite and even what looks like a bunch of insect eggs (I am not sure they are though).
Hard to know where to start on this gigantic 113.5 gram piece. It is just so big and has so much in it. There is what looks like 2 buds that have not opened yet, part of a messed up leaf, crane fly legs all over the place (no crane fly's though). There are (in no order here) lots of fungus gnats, midges, regular gnats, wasps, ants, flies, even a click beetle. There are so many animals inside (small ones) that I cannot even begin to count them. Every time I look at it, there are a half dozen new ones. This is quite the piece about 3 inches x 3 inches x .5 inches - and almost a quarter of a pound of amber.
This is a rare one. It comes from a parasitic larval form that only lives in spiders. Not only rare - but this is a perfect piece. This Acroceridae Ogcodes fly is an internal parasite of spiders. Adults of living forms can be found in vegetated or forested areas with females usually in search of a spider host or feeding on the nectar of flowers. The life span of the adult is very short (usually only 1 week). Larvae include a planidial first instar that actively searches out a host immediately after hatching from the egg. Larvae pass through 4 instars before emerging from the host and pupating. If you have not guessed, this is a very rare animal in Dominican amber.
