Did You Know…
Males perch in gullies to await females. First-stage caterpillars overwinter, complete their feeding the next spring, diapause in the summer as fully-grown caterpillars, then pupate and emerge as adults in the fall. A versatile and well-adapted butterfly, this may well be our most common orange-colored skipper late in the summer season.
