How rare are Lacwings in Dominican Amber? we've seen 4 in person, we've collected more Lacwings in Burmese and New Jersey amber than in Dominican amber.

from wikipedia..."The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order contains some 6,010 species. Traditionally, the group that was once known as Planipennia, with the Neuroptera at that time also including alderflies, fishflies, dobsonflies and snakeflies, but these are now generally considered to be separate orders (the Megaloptera and Raphidioptera). Sometimes the name Neuropterida is used to refer to these three orders as a group. This is either placed at superorder rank, with the Endopterygota becoming an unranked clade above it, or the Endopterygota are maintained as a superorder, with an unranked Neuropterida being a part of them. Within the endopterygotes, the closest living relatives of the neuropteridan clade are the beetles. The common name lacewings is often used for the most widely known net-winged insects - the green lacewings (Chrysopidae) - but actually most members of the Neuroptera are referred to as some sort of "lacewing".

The adults of this order possess four membranous wings, with the forewings and hindwings about the same size, and with many veins. They have chewing mouthparts, and undergo complete metamorphosis.

Neuropterans first appeared during the Permian Period, and continued to diversify through the Mesozoic Era.During this time several unusually large forms evolved, especially in the extinct family Kalligrammatidae, often referred to as "the butterflies of the Jurassic" due to their large, patterned wings.

Neuropterans are soft-bodied insects with relatively few specialised features. They have large lateral compound eyes, and may or may not also have ocelli. Their mouthparts have strong mandibles suitable for chewing, and lack the various adaptations found in most other endopterygote insect groups.

They have four wings, which are usually similar in size and shape, have a generalised pattern of veins. Some Neuropterans have specialised sense organs in their wings, or have bristles or other structures to link their wings together during flight.

The larvae are specialised predators, with elongated mandibles adapted for piercing and sucking. The larval body form varies between different families, depending on the nature of their prey. In general, however, they have three pairs of thoracic legs, each ending in two claws. The abdomen often has adhesive discs on the last two segments.

The larvae of most families are predators. Many chrysopids eat aphids and other pest insects, and have been used for biological control (either from commercial distributors but also abundant and widespread in nature). Larvae in various families cover themselves in debris (sometimes including dead prey insects) as camouflage, taken to an extreme in the ant lions, which bury themselves completely out of sight and ambush prey from "pits" in the soil. Larvae of some Ithonidae are root feeders, and larvae of Sisyridae are aquatic, and feed on freshwater sponges. A few mantispids are parasites of spider egg sacs.

As in other holometabolic orders, there is a pupal stage, generally enclosed in some form of cocoon composed of silk and soil or other debris. The pupa eventually cuts its way out of the cocoon with its mandibles, and may even move about for a short while before undergoing the moult to the adult form.

Adults of many groups are also predatory, but some do not feed, or consume only nectar.

The understanding of neuropteran phylogeny has vastly improved since the mid-1990s, not the least courtesy of the ever-growing fossil record.[1] In 1995, for example, it was simply known that the Megaloptera and Raphidioptera were not part of the Neuroptera in the strict sense, and the Mantispoidea and part of the Myrmeleontoidea were the only groups that could be confirmed by cladistic analysis.[5] Though the relationships of some families remain to be fully understood, most major lineages of Neuropterida can nowadays be robustly placed in an evolutionary context.

Kalligramma haeckeli fossil (Kalligrammatidae)Apart from a few groups that are quite basal or of uncertain position, the net-winged insects can be divided into two suborders, the Myrmeleontiformia and the Hemerobiiformia. The primitive Nevrorthidae, the most ancient group of living neuropterans, are sometimes considered a third suborder Nevrorthiformia or included in the Hemerobiiformia and more specifically in the Osmyloidea. But actually they are better considered a very basal lineage.

Description
This is an authentic Dominican Amber Gemstone excavated in the La Bucara Amber Mine in the early part of 2011.

Dominican Amber
In the Dominican Republic, Hymenaea trees are called Algorrobo. The Hymenaea tree exudes vast amounts of resin which over millions of years of pressure hardens into amber. Generally amber is found because a landslide along a steep slope in the mountains exposes veins of black lignite. If the lignite contains amber it is gradually extracted by digging along the vein with picks and shovels. After the amber is found it is chiseled by hand out of the shaft walls, put into burlap sacks and passed out of the mine where it is separated from the rock by machete. Larger chunks of amber make it possible to view inclusions almost immediately by holding the amber up to sunlight to determine if a large inclusion has been discovered. Fossil bearing amber is polished locally.

About Us
We have been collecting amber in the field and prepping rough fossil amber specimens since 1993. Photographs of our specimens have appeared in National Geographic, Nature, Science, Scientific American, Discover, Time, Newsweek, The New York Times and others. We have been featured in PaleoWorld's The Amber Hunters. We offer authentic museum quality Dominican Amber display specimens of rare insects in amber and also authentic rare Dominican rough unprepared amber for sale. Our collections include museum quality rare insects in amber, unusual botanicals and flowers in amber and also rough unprepared Dominican Amber gemstones. We have traveled many times to the Dominican Republic where we have chiseled beautiful amber gemstones out of the lignite layers deep in the amber mines north of Santiago. We have excavated in the Palo Quemado and Los CaCaos blue amber mines and also in La Nueva Toca and the world famous La Toca amber mines way up in the mountains north of Santiago. For many years we have extensively collected mid Cretaceous New Jersey amber in the Raritan formation of central New Jersey and have traveled many times to collect late Cretaceous and early Paleocene amber in the Hanna formation of eastern Wyoming. We have collected mid Cretaceous amber in the Black Creek formation of eastern North Carolina and we have spent weeks collecting mid Cretaceous amber in the northern most Tundra of Alaska. Some of our most recent collecting trips have been in October of 2003 to the western Aleutian Islands some 1000 miles west of Anchorage to explore and collect Miocene amber, August of 2004 and April of 2006 we were back in the Dominican Republic to collect Miocene amber from the Palo Quemado amber mines which have recently closed due to the miners finding little amber, we were back to the Dominican Republic in April of 2006 to video in the La Toca amber mines, and most recently in August of 2007 we excavated in La Toca and La Bucara. The La Toca amber mines had much water whereas on the other ridgeline the La Bucara amber mines were nearly dry! We collected much amber from both La Toca and La Bucara. Recently in January 2010 we have collected at a new site of early Eocene amber in Asia. As these specimens are examined and prepared we will post some additional photos of this new locality.

We have donated many hundreds of amber specimens to museums in the United States and have several dozen new species of insects in amber named after us. We have examined several thousand specimens of rough Burmese amber and have prepped many new Burmese fossil amber specimens. We have traveled to Europe with colleagues to examine unusual spectacular Dominican Amber specimens in private collections and we consider the amber curators of the museums in Santo Domingo, Puerto Plata and New York City our friends. Exploring for and collecting amber along with the examination and research of amber is our passion.

Our amber comes direct from the Dominican Republic amber mines east of the world famous La Toca amber mine. These specimens do not go through any middle men, we acquire these specimens from the miners and mine owners directly at the amber mines.
