Western Spotted Cucumber Beetle ~ Adult by 

Taken at Whitewater Draw, Az 2010 w/ Canon Powershot sx10is


The spotted cucumber beetle (Diabrotica undecimpunctata) is a major agricultural pest insect (see also cucumber beetle). In the adult form it eats and damages leaves of many crops, including cucumbers, soybeans, cotton, beans and many others. In the larval form, which is known as the southern corn rootworm, it tunnels through the roots of young plants, stunting or killing them. These native pests have a wide range of host plants, but will readily infest a field of crop plants, most notoriously corn.

Adult beetles are greenish-yellow with six large black spots on each elytron. They are about half a centimeter long. The larvae are yellowish and worm-like.

The spotted cucumber beetle has three subspecies, each with a different common name;

  • the Spotted cucumber beetle (a.k.a. Southern corn rootworm) is Diabrotica undecimpunctata howardi
  • the Western cucumber beetle is Diabrotica undecimpunctata tenella
  • the Western spotted cucumber beetle is Diabrotica undecimpunctata undecimpunctata.

My goal is to get my name out there among the vast ocean of Natural photographers. To be known for my skill with a Point & Shoot~

My images are not photo shopped. They have only been adjusted with basic sharpening, contrasting & saturation techniques. I believe that in order to appreciate Nature, you have to capture it as it is, naturally.

    This is a great shot – the green is striking; I usually think of them as being more yellowy. We have the striped & the spotted versions here in the northeast, but the striped is a lot more common.

  • I had fun taking shots of him, there were a lot of them out there while we were waiting for the cranes~☺ Thank you!

    I love the vivid green against the bark and I like that you provide the information on the beetle! It may be a pest, but it sure looks pretty!

  • I agree! He is pretty and I was happy to see him. First bug shot of the season, I look forward to other insects this year (so to speak)…lol
