I get a kick out of pieces like this. There is a lot here - a tropical stingless bee, Hymenoptera, Meliponini, genus Proplebia. On top of that there is a winded termite, Isoptera and a very special unknown animal (just not sure on this.) This is sure to be an interesting piece of Dominican amber.
This is one cool spider. It is commonly called the oil-can spider. Take a close look at the body and you will see why they are called this. They are not common in Dominican amber (although I would not say they are rare). There is a little confusion in terminology of this genus: it is either Lasaeola or Dipoena (family Theridiidae). The amber is small and thin.
A rather unusual situation with this piece. It contains a moth fly, Diptera, Psychodidae. While that is not very unusual, this is a female that is laying eggs. Often in the throes of difficult situations, females will often lay eggs (assuming they are pregnant). This is one such unique situation.
Homoptera, Fulgoroidea - there are 2 planthoppers in this piece of Dominican amber. One planthopper is very small. In fact the small one looks as though there is a mite on one of the back legs (but upon further inspection, it is not a mite)- really cool. Finally there is a large springtail, Collembola (not shown in pictures).
