Explanation of Names
Apiomerus Hahn 1831
Greek apios 'long' + meron 'thigh' (Amyot & Serville 1843)
~110 spp. total(3); currently, 10 spp. are known in the US (with another species described by Szerlip(1) presumably awaiting official description a la(2)):
crassipes group (6 species): A. californicus, A. cazieri, A. crassipes, A. floridensis, A. montanus, A. spissipes
pictipes group (1 species): A. flaviventris
longispinis group(?)(1 species): A. longispinis
subpiceus group(?)(2 species): A. immundus, A. subpiceus
12-20 mm
Variably colored: red with blackish-brown markings or brown with yellowish markings. Dense short hair on head, thorax, and legs. Distance between simple eyes greater than the distance between compound eyes. 2nd antennal segment rather comblike, not subdivided into small ringlike units. Nymph is dark and reddish.
n. US to Argentina; transcontinental in the US, except the Pacific Northwest, with greatest diversity in the southwest
Meadows, fields, gardens, deserts, mountains, coastal regions
Other insects, especially bees
Life Cycle
Eggs are attached to foliage. Nymphs, like adults, are voracious predators. 1 generation or more a year in the North.
Some spp. have sticky material on foretibiae to hold prey(4). Females use these plant resins in maternal care(2).
our only representative of the primarily neotropical tribe Apiomerini Amyot & Servile 1843 ("New World Resin Bugs"), that contains 12 genera(3)
