The defensive secretion of the carabid beetle
Pasimachus subsulcatus is a concentrated solution (up to 90%) of carboxylic acids, amounting to about 1% of body mass. It contains three major components (methacrylic, tiglic, and angelic acids) and four minor components (isobutyric, 2-methyl-butyric, isovaleric, and senecioic acids). In the single population of this large flightless beetle that was examined, the relative ratio of acidic components was remarkably constant from individual to individual. Key words Defensive secretion aliphatic acids beetle Coleoptera Carabidae Pasimachus subsulcatus carboxylic acids
