Giant Water Bug from Argentina

What is this bug?
February 7, 2010
Hi there, I have seen this bug for the first time in my life and in the two years I have been living in my place. I live in an apartment, first floor with a patio and some plants in pots. No grass or dirt. Even thou I have seen pretty much variety of insects that took my attention several times. I have remembered this site and decided to start sending you pics of what I just find interesting to share. As you see the insect is dead but I have found one alive but took it away because I don´t really know if it can bite. We are in summer now and these ones appeared after 3 days of continuous rainy days. Thanks for you help.

Giant Water Bug

Hi Fred,
This is a Giant Water Bug in the family Belostomatidae.  Most of the examples we see are from the genus Lethocerus, but your specimen is from one of the other genera, probably Belostoma, or possibly Abedus.  Giant Water Bugs are aquatic predators that can also fly quite well, a capability they use when their ponds dry out.  They are also attracted to lights, and that may be the reason it was attracted to your apartment.  Giant Water Bugs can bite painfully if provoked or carelessly handled, and in the U.S. they are commonly called Toe-Biters as well as Electric Light Bugs.
