Bristletails are rarely found in Dominican amber. The order Thysanura, is characterized by three long tails and long slender antennae. The body is shrimp-like. Thysanura, in particular, may be the direct ancestor of winged insects. There are also 3 or 4 fungus gnats, Diptera, Mycetophilidae. This is a good piece.
Interesting piece. This has a large long legged fly, Diptera, Dolichopodidae (?), an unknown beetle (not sure about this one), two fungus gnats, Diptera, Mycetophilidae and a moth fly. It has some other stuff also. A lot of the animals were caught at the 'interface' of two layers of resin - easily seen in the photo.
No insects here - just color. And what a color this is, just magnificent. This is the PREFECT piece to be made into a pendant. A thin gold band around it with a hook so a chain can go through it and you have the ideal gift for anyone at anytime. This is an impressive piece of Chiapas amber.
Ya' gotta love this one. There is a complete cricket. The long antennae are both present and all the body parts. In fact you can discern the body markings. Quite an impressive fellow. Not far from him is the largest springtail I have ever seen (they are normally VERY small). Thrown in a couple wasps and this is quite the piece. Finally there is a fungus gnat, Diptera, Mycetophilidae.
This is probably the most perfect chunk of amber I have ever seen. Perfectly clear, this weighs 239 grams. I am offering it for 'only' $6 per gram - MUCH less than it should be. The is what I consider a wholesale price. This is a museum quality piece of amber. You will never see a better piece of Dominican amber than this. It is about 4 x 3 x 2 inches. You will love these pictures and this video.
If you recognize the wings, then you know that this is a mayfly Emphemeridae. This is a male since the cerci are so long. This specimen with all three cerci intact is very rare. Mayflies are characterized by protruding eyes. Hind wings are small and rounded or very reduced. Mayfly adults enjoy a life span of no more than two days. On the transition from nymph to adult stage, they fly from the surface of the water for mating, but do not feed. They complete their mating process and die after one or two days. This specimen is perfect.
