Guides
Althaeus folkertsi
velvetleaf seed beetle
Althaeus folkertsi, the velvetleaf seed beetle, is a seed weevil in the subfamily Bruchinae (formerly treated as family Bruchidae). Adults are extremely small, measuring 1.5–2.5 mm in length. The species is associated with velvetleaf (Abutilon theophrasti) and related mallows, developing within the seeds. It occurs in North America.
Niesthrea
scentless plant bugs, hibiscus scentless plant bugs
Niesthrea is a genus of scentless plant bugs in the family Rhopalidae, tribe Niesthreini. The genus comprises approximately 20 described species distributed primarily in the New World, from the United States through Central and South America. Species in this genus are associated with plants in the family Malvaceae, with some species serving as important biological control agents against agricultural weeds such as velvetleaf (Abutilon theophrasti). The best-studied species, Niesthrea louisianica, exhibits striking orange, black, and white coloration and has been extensively investigated for its potential in integrated pest management programs.
Niesthrea louisianica
Hibiscus Scentless Plant Bug
Niesthrea louisianica is a small scentless plant bug in the family Rhopalidae, measuring 6.5-8.5 mm in body length. It is native to North America, ranging from New York to Florida and west to California, with populations also present in Hawaii. The species is a specialist feeder on plants in the mallow family (Malvaceae), including Rose of Sharon (Hibiscus syriacus), cotton, okra, and velvetleaf. It has been investigated as a biological control agent for the agricultural weed velvetleaf (Abutilon theophrasti), capable of reducing viable seed production by 98-99% through feeding damage to reproductive structures.
