Entomology (Study of Bugs)/1000s of brown iridescent eggs



I live across from a creek on the Delaware Bay in New Jersey.
I was under my house yesterday on my knees in the sand crawlspace. At one point the sand gave way under my knee, only to reveal a massive pile of tiny brown iridescent eggs. (I assume they are eggs.) They were smaller than the head of a pin and perfectly round. There were hundreds and hundreds of them. Any idea what they might be?

Many many thanks

Dear Erin - Without being able to see an image of your mystery objects, I am hesitant to even guess at what they might be. I cannot think of anything right off that might lay such a large mass of eggs in the situation you describe. You might try submitting a sample of them to your nearest office of Rutgers University Cooperative Extension Service to see if anyone there might be of assistance; see for contact information.
Sorry not to be of more immediate assistance,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
