Shallow water of boreal wetlands; the Michigan site at the edge of an old beaver flooding.
This rare Utricularia, though irregularly circumboreal, is still poorly known in eastern North America, though long known near to Michigan in the Lake Superior region of Ontario. It was discovered in Michigan by R. Routledge in Keweenaw County in 2019. Similar to U. intermedia in having dimorphic shoots, U. ochroleuca has at least a few traps on the flat green shoots in addition to those on the colorless shoots. As well, the spurs are only about half as long as the lower lip, while in U. intermedia, the spur is large, only slightly shorter than the lower lip. This species has also been thought by some to have originated as a hybrid of U. intermedia and U. minor, though it seems to form discreet populations. See Crow (2015) for additional information.
