These bugs were on a tree in southern Costa Rica on the Pacific coast near Uvita. They were found today, Jan. 22, 2015 at 2 pm. Related to Giant Mesquite Bug? They were between 1.5 and 2 inches in length and they were found beside a dry stream bed.

Immature True Bugs
Nymphs of Coreid Bugs:  Pachylis pharaonis

Dear Cathy and Lisa,
We are not certain these immature True Bugs are in the same genus,
Thasus, as the Giant Mesquite Bugs, since their colors and markings are different than other images we have seen, but the flattened segment on the antennae are consistent with the genusThe closest match we can find at this time is this individual from Guatemala that is in our archives.  Perhaps your individuals are a regional color variation or a not well documented species.
