1 sp. n. of Mex. (1)

Unit tray of Labidomera clivicollis (Kirby) curated in the TAMUIC.

NM-FL-ME-ND/ se. Can. / n. Mex. (1)
Meadows, roadsides, with milkweed, especially wetlands with Swamp Milkweed (Asclepias incarnata).
mostly: May-Oct (BG data)
Foliage, flowers, of milkweed, especially Swamp Milkweed (Asclepias incarnata), but also found on Common Milkweed (Asclepias syriaca). Also on swallow-wort (Cynanchum) and twinevine (Funastrum = Sarcostemma). (2)
Life Cycle
Often overwinter as adults among leaves of such plants as mullein (Verbascum). Adults mate on or around milkweed. Eggs are cemented to the underside of leaves. Larvae feed on leaves, and drop to ground to pupate. (3)

Part of the orange and black milkweed mimicry complex, which includes Monarch Butterfly, Red Milkweed Beetle, milkweed bugs, and at least one assassin bug.
Larvae and adults of this species cut several side-veins of a milkweed leaf prior to feeding, to reduce the sticky latex that would otherwise be produced at their feeding sites. (4)
