Jessica Mellinger

I can answer questions about invertebrates native to California, including insects commonly found in homes. If you have an identification request, please attach a photo to your question.

Sue Kayton

Silkworm expert. Have raised them as a hobby for 20 years. I do not identify unknown insects.

Ed Saugstad

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.

Nathan Riggs

I currently live in San Antonio, TX and have expertise in identifying insects, many types of spiders, and other arthropod critters that infest lawns, ornamentals, structures, trees, pets and livestock. Mites are not a strong point of mine. I'm not a licensed doctor, so I cannot provide medical diagnosis of conditions possibly related to insects or other arthropods. If you've got an interesting photo for me to see, attach it to your question, or let me know and I'll give you my email so the picture will get to me. If you have hosted an insect photo on a website, please include the link so I can go look at it and provide a faster ID for you.

Walter Hintz

I can answer any questions about insects and spiders.

Eric R. Eaton

I can answer most questions related to the identification of "mystery bugs" in NORTH AMERICA, including spiders. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. No technical questions about insect physiology.

Jack DeAngelis

Maxed Out
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
