Flea Beetle

.

A very cool beetle for your consideration.

Photographed at Santa Anna National Wildlife Refuge on the Rio Grande River, Texas

Eight-spotted Flea Beetle
Omophoita cyanipennis octomaculata


The adults are very small to moderately sized Chrysomelidae (i.e. among beetles in general they are on the smallish side).

They are similar to other leaf beetles, but characteristically have the hindleg femora greatly enlarged. These enlarged femora allow for the springing action of these insects when disturbed. Flea beetles can also walk normally and fly. Many flea beetles are attractively colored; dark, shiny and often metallic colors predominate.

Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding these holes may coalesce into larger areas of damage. Some flea beetle larvae (e.g. of Phyllotreta species) are root feeders.

In adverse weather conditions (rain, for example) some flea beetles seek shelter in the soil. At least a few species(Phyllotreta cruciferae and P. striolata) prefer warm, dry weather. The German name Erdflöhe (literally "earth fleas") refers to their jumping ability and this behavior of hiding in the soil.

What a wonderful little bug. People always look at me funny because I am always picking up little beetles and other small bugs and handing them to my children, and vice`versa, No words exchanged, just eye contact and then their eyes light up as they study them and off they go..Not sure when this started, but as they get older these moments are more and more precious to me.. the smaller the bug the happier my 10 yr old is.. lol.. thanks Troy and Martha,, have a beautiful weekend.

That fella should have been in PhotoHunt also - amazing colours.

Doug Taron said...

Excellent photo pf a stiking species. My entomology friend John, whom I go collecting with, is an expert in the Chrysomelidae. He's taught me a lot about them.

Kahshe Cottager said...

I have never seen one of these before. I would have mistaken it for a ladybug I think!

Have a wonderful weekend!

CrazyCath said...

There is so much work gone into this post. Thank you. It truly is interesting to not only see different critters around the world, but also to learn a bit about them. I had no idea this beetle existed!

Thanks for sharing.

Wonderful photo of this tiny insect and lots of interesting (if mostly unpronounceable) information. Now... if I can just find a way to include "Omophoita cyanipennis" in a conversation! To do that, I probably need to be talking to Marvin at Nature in the Ozarks!
Truly, T & M, I enjoyed the post, and really liked the explanation of how the creature received its name.
Reading blogs can be very educational. :)

I always have a few choice words to say when I flea beetle takes a flying leap while I'm trying to photography it. They are quick to spook. Great capture.
