Estigmene acrea

with 32 comments

“What’s that white thing?” That’s what I wondered when I glimpsed a little white area on one of several distant narrowleaf sumpweed* plants (Iva angustifolia) that were flowering in my neighborhood on September 29th. After I walked closer I saw that it was a moth**, which I take to be Estigmene acrea, known as the saltmarsh moth. An even closer look revealed that on the sumpweed it had laid some tiny pearl-like eggs, several clusters of which you can discern in the photograph. The three larger round yellowish areas interspersed across the bottom of the picture were out-of-focus broomweed flowers (Amphiachyris dracunculoides).

* Sumpweeds (which you might be surprised to learn that botanists put in the sunflower family) are close relatives of ragweeds. Like those better-known plants, sumpweeds’ airborne pollen at this time of year causes hayfever in susceptible people, including this photographer who sometimes sneezes his way through the autumn landscape for the sake of pictures from nature.

** Modern English moth developed from Old English moððe, where the ð represented the sound we now spell th. People must have found it troublesome—as we would—to pronounce two th‘s in a row and therefore dropped one of them (along with the supporting vowel that followed, thereby reducing the word to a single syllable).
