Figure 1. Chemical compounds produced by L. heterotoma.

Total ion current chromatograms of (a) L. heterotoma female extract and the iridoid fraction of (b) female and (c) male extract. Compound p5 is (−)-iridomyrmecin and p6 is (+)-isoiridomyrmecin. The inserts in (b) and (c) show their structure and absolute configuration. Compounds p1 and p2 were tentatively identified as iridodials; p7 was tentatively identified as a third iridomyrmecin. p3 and p4 were behaviourally inactive and thus not identified.
