Explanation of Names
Xanthogaleruca luteola (Müller 1766)

6―8 mm
Native to w. Palaearctic(1), adventive in our area (CA-FL-NS-BC)(2)(3)
hosts: elms (Ulmus)(2)
Life Cycle
Overwinter as adults in sheltered dry places. Hibernation can begin in August; eggs are laid in late May or early June, larve begin to hatch in about a week and feed on the undersides of leaves for 2-3 weeks, then crawl down and pupate in bark crevices. There may be 1―2 generations with a partial 3rd generation per year. The first generation is the most injurious.(4)
first detected in Baltimore, MD in the late 1830s(2)(3)
Considered a pest of elms(2)

In addition to the occipital spot, X. luteola usually has a spot just above the antennae, rarely present in Trirhabda
X. luteola is usually found near places where elm trees have been planted. Trirhabda spp. usually occur in less disturbed areas.
