This is a cool piece. It is rather a dark amber color. There is a small primitive fly, Nematocera, but it has a very nice male winged ant, Hymenoptera, Dolichoderinae (?). There is a decomposition bubble emanating from the abdomen, which is not common in ants (termites, yes, ants no).
Nice size, very interesting piece. There is some surface glazing, but does not interfere at all with specimen. there is 2 tropical stingless bees that are inside an amber tube. That is, one amber flow caught the bees and then another and another flow came over them. The bees are visible, but are occluded by some air bubbles.
A very large piece of Dominican amber with a large leaf. Perfect. The amber is about 88 grams and about 3 x 2 x 1 inch in size. The single huge leaf is about 2 inches long. By the way, that is VERY large. This is the type of piece that sets a collection, it is even large enough to be the representative of a collection - as good as it gets.
An interesting piece. First, this does have a surface crazing - common in some of the Dominican ambers. But inside are a number of cool beetles, There are 7 bark beetles, Scodytidae and 2 Colydiidae beetles (cylindrical bark beetles, of the genus Bitoma. If you like beetles, this is a beetle fest.
Fun and informative. This does have a fungus gnat, Diptera, Mycetophilidae and 2 planthopper nymphs. This piece is cool, not because of the insects, but how it was formed. You can see that this is a cross section of a an amber tube. You can see the original amber flow and then successive layers of resin flows (like stalagmite).
If this picture on the left doesn't attraction your attention, nothing will. At first I thought this might be a mosquito, but I now think it is a female, long beaked fungus gnat, Nematocera, Lygistorrhinidae (or it could be Mycetophilidae). When it became stuck in the sticky resin, it laid it's eggs. You can see a rather large amount of detail on the egg case. There is a large spider and some other Dipterans, but the eggs and fungus gnat are what makes this stand out from the rest. There is a just a lot here.
