An energetic species that has three different color morphs. Although typically red and black, this species may also be yellow and black or orange and black.
Jadera haematoloma (Herrich-Schaffer 1847)
Range: United States, Hawaii, Caribbean, Mexico, Central America to Columbia and Venezuela
Hosts: Cardiospermum corindum (Faux Persil), Cardiospermum grandiflorum (Showy Balloonvine, Showy Heartseed, or Love in a Puff), Cardiospermum halicacabum var. halicacabum (Balloon Vine or Heartseed), Cardiospermum halicacabum var. microcarpum (Balloon Vine or Love in a Puff), Koelreuteria bipinnata (Chinese Flame Tree), Koelreuteria elegans (Chinese Rain Tree), Koelreuteria paniculata (Goldenrain Tree), Sapindus mukorossi (Chinese Soapberry), Sapindus saponaria var. drummondii (Western Soapberry), Sapindus oahuensis (Hawaii Soapberry), and Serjania brachycarpa (Littlefruit Slipplejack)
Physical description: About 10 to 14 mm in length. Black dorsal side with broad red lateral stripes on sides of head and pronotum (most distinct on pronotum); eyes are also red. May be orange or yellow in places that are typically red, depending on the color morph. Ventral side is dark except for margins of abdomen and posterior segment, which are red. Appendages are black. May resemble: J. diaphona (pronotum broader and longer; abdomen yellow) and J. pyrrholoma (much larger in overall size; narrower head)
