Caterpillars tied to widespread foal loss in 2001
Eastern tent caterpillars in Central Kentucky are mature, have dispersed from trees, and are on the move, leading experts to advise horse farm managers to move pregnant mares, if practical, to avoid contact with them.
Experts report the eastern tent caterpillar egg hatch will likely begin in mid-March for Central Kentucky.

Experts have reported that eastern tent caterpillars are now wandering and population levels are among the highest they've seen since the 2001, when Mare Reproductive Loss Syndrome hit Central Kentucky particularly hard.
Experts have reported that Eastern tent caterpillars are developing normally this spring and have just completed the egg hatch stage. Controlling the caterpillars is vital to area horse farms, as University of Kentucky research has strongly linked them with outbreaks of mare reproductive loss syndrome, which can cause late-term foal losses, early-term fetal losses, and weak foals.
The time is right for horse farms to implement control strategies. University of Kentucky experts report that eastern tent caterpillars and forest tent caterpillars are developing normally this spring with egg hatching complete and populations feeding, making this an optimal time for horse farms to assess caterpillar activity and implement control strategies while the larvae are still small and most susceptible.
Though there aren't indications of widespread high populations of the Eastern tent caterpillar, University of Kentucky officials said its an optimal time for horse farms to assess caterpillar activity and implement control strategies while the larvae are small and most susceptible.
