Plate 7.1. Natural history of Utetheisa omatrix (left panel). Adult male (top) larva feeding on seedpod of Crotalaria mucronata (middle) adult male courting a female (bottom). The yellow genitalic coremata are partially inflated and thrust toward the female. Natural history of Cosmosoma myrodora (right panel). Adult male resting on leaf of the larval host plant Mikania scandens (top) larva (middle) male courting female (bottom). The flocculent has been released and forms a cloud around the pair. 

Figure 12.3 Utetheisa ornatrix that were offered to the orb-weaving spider Nephila clavipes. The specimen on the right, rejected intact, was raised on one of its normal, pyrrolizidine alkaloid-containing food plants (Crotalaria mucronata). The one on the left, raised on an artificial diet devoid of alkaloid, was eaten. See also Figure 12.4. (From Eisner, 1982. American Institute of Biological Science.)...

Mucronatinine (56), a new alkaloid which is the major constituent of the seeds of Crotalaria mucronata Desv., is a diastereoisomer of retrorsine its structure was elucidated almost entirely by n.m.r. spectroscopy. ... 

The mode of attachment of the necic acid in crotastriatine (from Crotalaria striata) to the nedne (retronedne) has been investigated. Hydrogenolysis of crotastriatine gave a product, presumably the zwitterion (41) the i.r. spectrum of which indicated the presence of an intact a/S-unsaturated ester function, confirming the mode of attachment as in (40). Crotastriatine (40) is the acetate of nilgirine (42) which has also been found in Crotalaria striata (= C. mucronata). Acetylation of nilgirine (42) with acetic anhydride-perchloric acid gave crotastriatine (40).
