Ladybugs, aka ladybeetles (family Coccinellidae), are best known for devouring aphids, those pesky little critters that suck plant juices.
But have you ever seen ladybugs gobbling ants?
There's a three-way predator-prey relationship here. When aphids pierce plant stems, they leave behind honeydew excretions. Ants scurry to the honeydew and quickly alert their buddies. Soon, you'll see a long trail of ants marching toward the honeydew.
Now enter the ladybug, which is attracted--quite nicely, thank you--to both aphids and ants.
This little beetle will feast on aphids and ants much like we humans chow down on popcorn and jelly beans at a movie.
In the photos below, unsuspecting ants climbed a lavender stalk, only to meet their demise.
If you look on You Tube, you'll see a video of an apparently famished ladybug chowing down ants. The background music of Queen's "We Will Rock You" adds the finishing touch.
Want to learn more about ants? Check out professor Phil Ward's website. He's a noted myrmecologist (one who studies the taxonomy, evolution, biogeography and behavior of ants) and a professor of entomology at the University of California, Davis.
One of his former graduate students, Alex Wild, has incredible insect photography on his website, appropriately named myrmecos.net.
If you're accustomed to seeing ants crawl, wait a minute...some can actually jump.
Ants? Jump? Like leaping lizards?
Harpegnathos saltator, aka Jerdon's jumping ant, a species found in India, can indeed jump. It can leap a distance of about 10 centimeters (about 3.9 inches). It does this to catch prey and to escape sticky situations.
Christian Peeters, director of the Laboratoire d’Ecologie, Université Pierre et Marie Curie, Paris, will talk about Jerdon's jumping ant when he discusses his research at a noon lecture on Wednesday, April 15 in 122 Briggs Hall, University of California, Davis. His topic is “Recurrent Selection Against Winged Queens in Ants, and Shifts in Life History Traits.”
This exquisite photo (below) of Jerdon's jumping ant is the work of entomologist-insect photographer Alex Wild, who received his Ph.D. from UC Davis (his major professor was Phil Ward). Wild is now a postdoctoral researcher at the University of Illinois. You'll want to visit his Web sites often to view his amazing work.
