Stinging Rose Caterpillar (Parasa indetermina) Contacting this slug caterpillar causes a painful sting and the contact spot eventually swells and remains painful for hours or days. Fortunately this is a rare caterpillar.

White Flannel Moth, Norape ovina (Sepp, 1848), and Saddleback Caterpillar Moth, Acharia stimulea (Clemens, 1860), caterpillars feeding on Eastern Redbud. Both stinging caterpillars. Near Brentsville, Virginia, USA. Photo by David L. Govoni ©2017.

A good friend of ours, Stan Malcolm called me this morning to let me know that he had found an Isa textual caterpillar. He regularly walks along the air line trail and is an experienced naturalist, entomologist and photographer. You can visit his blog at: www.performance-vision.com/airline/index.htm

Specimen was imaged live, stack of 85 images.

The Macropod is a rigid, portable photomacrography system, which allows the user to make razor sharp, fully focused photographs of small sized specimens at 18 to 26-megapixel resolution. It overcomes the extreme Depth of Field (DOF) limitations inherent in optics designed to image smaller specimens. Normally, lenses designed for macro will only render a very small fraction of the depth of targeted specimen in sharp focus at any one exposure. The Macropod allows the user to select and make multiple exposures in precise increments along the Z-axis (depth) such that each exposure’s area of sharp focus overlaps with the previous and next exposure. These source images are then transferred to a computer and merged by an image-stacking program. The stacking program (Zerene Stacker by Rik Littlefield) finds and stitches together only the focused pixels from each exposure into one image. The Macropod integrates industry-leading components in a novel and elegant way to achieve these results.
