Howdy, BugFans,<\/p>\n

The BugLady found this velvety, deeply maroon caterpillar at the Land Trust\u2019s CESA site on a fine June day. It\u2019s the larva of a Straight-toothed sallow moth (Eupsilia\u00a0vinulenta<\/em>) (probably). (Full disclosure \u2013 the experts caution us that the only way to positively ID an Eupsilia<\/em> caterpillar is by rearing it to an adult.)<\/p>\n

Sallows are a group of Owlet moths (family Noctuidae<\/em>) that are pretty hardy \u2013 depending on the latitude, moths may be active all winter, or overwintering adults may emerge from hibernation, fly around, and visit maple sugaring operations on balmy winter days when the temperature climbs above freezing (For a scenic side trip, see \u201cInsects attracted to Maple Sap: Observations from Prince Edward Island, Canada<\/a> <\/i>.”). One source reported seeing the moths searching for warmer shelters on sub-freezing nights, shelters they locate using their antennae.<\/p>\n

In\u00a0Caterpillars of Eastern North America<\/u>, David Wagner notes that sallows readily come to sugar baits (Eupsilia<\/em> species \u201cgather by the hundreds at beer or sugar or other baits\u201d). He recommends to us Holland\u2019s description of baiting moths, and the BugLady is grateful to the Alberta Lepidopterists Guild for posting it<\/a> <\/i>. They just don\u2019t write science like that anymore.<\/p>\n

The Moth Book<\/u> by W.J. Holland was published in 1904, and with 48 (XLVIII) plates crammed with images, it was for decades the moth Bible. (The down side was that moths are pictured like the pinned specimens that they are, with their wings spread, rather than perched naturally.) By 1926, it had joined five other books in a set called The Nature Library<\/u>, and the set that the BugLady grew up with her nose in probably belonged to her Mom.<\/p>\n

Kirk Mona, in his Twin Cities Naturalist<\/em> blog found an alternate name for the Straight-toothed sallow \u2013 he says \u201cThe name <\/em>the Satellite comes from the little spots that seem to orbit like satellites around the larger spot on the fore wings. What a cool name! It is much cooler than ‘Straight-toothed Sallow’<\/a> <\/i>.<\/em>”<\/p>\n

Adults are variable in color, from pale<\/a> <\/i> to brown, to rust<\/a> <\/i>. They mate in late winter and early spring. Here are the eggs<\/a> <\/i>. Adults nectar on early tree flowers like red maple.<\/p>\n

Caterpillars<\/a> <\/i> are somewhat generalist feeders, found on the leaves of an assortment of shrubs and trees like box elder, oak, cherry and maple. Wagner says that younger larvae are \u201cnew-leaf specialists that fashion crude leaf shelters in young leaves<\/em>,\u201d and they may use the abandoned shelters made by other caterpillars. According to Owlet Caterpillars of Eastern North America<\/u>, older caterpillars are found on the in leaf litter on the ground and may feed on low-growing plants or on plant material (like old flowers and catkins) that\u2019s fallen off of trees.<\/p>\n

On another front, Monarch butterflies are starting to reach our southern borders.\u00a0 Here\u2019s info about the status of Monarch populations in 2021<\/a> <\/i>. And here\u2019s an animated 2021 Monarch migration map.<\/a> <\/i><\/p>\n

Go outside \u2013 look for moths (and listen for owls, too)!<\/p>\n
