For most of my career in entomology, I was only interested in economically important arthropod species in agriculture and disregarded the rest. In July 2015, something "clicked" and suddenly I wanted to learn about every local invertebrate and document them through macro photography. For the first six months, I used a point-and-shoot camera (Coolpix L820). Later, I started experimenting with a Canon 7D body, a challenging Canon MP-E 65mm 1-5X lens, and a Yongnuo ring flash. The Venus Optics KX‑800 Flexible Macro Twin Flash VEKX800 has proven hard for me and produces a low rate of acceptable images. It gets very little use. However, I suspect the problem is not the flash, but my technique. In regards to flash systems, the game changer for me has been my recent acquisition (June 2017) of a Yongnuo YN-24EX TTL Macro Twin Lite Flash. When coupled with a home-made flash diffuser, this flash unit consistently produces acceptable results (and its low price is hard to beat). For bugs over 2 cm long, I use a Canon Macro Lens EF 100mm 1:2.8 paired with a Canon EOS 70D. I am never satisfied with my bug pictures and I am always hoping to find ways to improve.

Lately, sweeping has become my favorite technique to catch bugs for its convenience and effciency. After sweeping, I capture the bugs in plastic vials by the means of an aspirator. Then, take them back home alive for photos and release them once done. When the insects are too active, I slow them down by briefly placing them in the refrigerator and photograph them while they recover. These photos are shot inside a white, 30" X 30" "light box" or "tent cube" to reduce their opportunities of escaping into the house. Unfortunately, at times I need to kill the specimens given that they have to be perfectly still for focus-stacking to work or when I need to image their wings. I would love to learn how to perform focus-stacking on live bugs, in the field, as some outstanding photographers seem to do with ease.

I am not a taxonomist, but I am passionate about learning to recognize as many insect species as I can as well as to educate myself and others about their lifestyles, relationships, and diversity. I am grateful to BugGuide Editors and Contributors who constantly help me identify and better understand bugs. I post all of my bug photos on BugGuide and the ones of invertebrates in Far West Texas, southern New Mexico, and southeastern Arizona can be found at:

In a nutshell: I have experience in extension, research, teaching, administration, and agrochemical industry. My applied entomology background includes IPM in cotton, pecan, small grains, field crops, and vegetables.

NOTE: If I were to die, I would like my photos to remain here on BugGuide.
