Entomology (Study of Bugs)/Expert Profile

Ask A Question


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.

What do you like about this subject?

Insects are one of the most diverse and interesting groups of creatures on the planet. They are found everywhere except the poles and the deepest oceans.

What do you still hope to achieve/learn in this field?

Better public understanding of insects and the benefits of having insects around. Only 2% of all insect species are actually pests and spoil it for the rest of the insect world.

Something interesting about this subject that others may not know:

Texas is home to more native and migratory butterfly species that any other state in the U.S.!

Something controversial or provocative about this subject

1) During their sleep, people swallow an average of 8 spiders during their lifetime! Urban legend or truth??? 2) There are ~1 million species of insects identified on earth, but experts believe there may be as many as 30 million species of insects total.

This picture is super fuzzy, but my first impression is that this is a ladybug larva based on the size and shape.  My second impression is that this might be a moth of some kind.    Do a search for ladybug
