SPIDER AFTER THE RAIN

This big spider wove its web between one of the bird boxes and the ferns and flowers below in our front yard. After a rainy night in late August I found the web full of water droplets and thought this was an interesting subject to photograph. While approaching the web with the 150 mm macro lens on camera, the nest started to vibrate a little and the spider came suddenly out of the bird box, and tried to find out if someone fell victim in his artfully designed web.

In order to have sharpness for both, the water droplets and the spider, I closed the lens down to f/8. Because I was really close the depth of focus was only 10 mm, less than half an inch, and the background remained still nicely blurred.

My brother-in-law Don gave me the hint about a patch of alfalfa next to his pig nursery, where hundreds of butterflies were feeding nectar from the blossoms. Most of them were Painted Lady (Vanessa cardui), one of the most widespread butterflies in North America. Adults may not survive in freezing temperatures and so most of them overwinter in the south and Mexico. Their flight and wing beats are erratic and fast and it was difficult to pre-visualize how the photos would turn out.

Spider paralyzing Painted Lady butterfly

One butterfly got my particular attention while I tried to follow it with the camera. The insect suddenly stopped moving and remained still with its wings spread out. Having a closer look revealed that the Painted Lady was ambushed by a spider. While the butterfly was in a feeding frenzy, the spider used its chance and paralyzed its victim. Well, they all have to live…
