In Texas this March, Erika and I saw a Variegated Fritillary. Note the black-ringed orange spot on each forewing: a distinctive field mark for this butterfly. These fritillaries are common across most of the southern United States (and south into South America). During some summers they spread north, even into central Canada. The larvae favor a number of plants, including flax and violets; adults drink from a wide variety of field weeds.
