Entomology (Study of Bugs)/what is this type of but


I have noticed that my column in the front of my house has a a bunch of spots on it that  looks like a lot of mud splatters.  I was able to see the bug they are very very tiny black insects that fly. What is this.

Dear Melissa - I cannot see enough detail in your image to be absolutely certain, but I believe that these might be tiny wasps emerging from moth eggs - see for an example. Some parasitic wasps (such as those in the families Mymaridae and Trichogrammatidae) are so small that they can complete their development inside a single egg of another insect. Parasitized eggs usually turn black.

Hope this helps,

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.
