The Lady Bird Johnson Wildflower Center Fauna Project |
Our five participants enjoyed mostly cloudy warm weather during this week's survey. Caterpillars can sometimes have a very hard life. The Monarch shown below was harrassed by a tiny parasitic wasp which caused the caterpillar to twitch and jerk around. The Yellow-striped Armyworm (also pictured below) had it even worse; it not only had a large cluster of wasp larvae feeding on it, but there were also four tachinid fly eggs. The maggots that hatch out of those eggs will feed internally on their victim.
