Amygdalin (from Ancient Greek: ἀμυγδαλή amygdalē 'almond') is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels, pips or stones) of apricots, bitter almonds, apples, peaches, cherries and plums, and in the roots of manioc.
Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride poisoning. [2] There is no specific test for arsine poisoning, but it may leave a garlic smell on the victim's breath. [2]
Dyeing poison dart frog (Dendrobates tinctorius) Most species of poison dart frogs are small, sometimes less than 1.5 cm (0.59 in) in adult length, although a few grow up to 6 cm (2.4 in) in length. They weigh 1 oz. on average. [7] Most poison dart frogs are brightly colored, displaying aposematic patterns to warn potential predators. Their ...
Unpalatability, broadly understood, can be created in a variety of ways. Some insects such as the ladybird or tiger moth contain bitter-tasting chemicals, [14] while the skunk produces a noxious odor, and the poison glands of the poison dart frog, the sting of a velvet ant or neurotoxin in a black widow spider make
The poison is generally collected by roasting the frogs over a fire, but the steroids in P. terribilis are powerful enough that it is sufficient to rub the dart on the back of the frog without killing it. In the northern Kalahari Desert, the most commonly used arrow poison is derived from the larva and pupae of beetles of the genus Diamphidia ...
The Food Safety Authority of Ireland advises against eating either bitter or sweet varieties of apricot kernel due to the risk of cyanide poisoning and advises consumption be limited to one to two kernels a day for an adult. They also advise against consuming bitter almond for the same reasons. [13]
HCN has a faint bitter almond-like odor that some people are unable to detect owing to a recessive genetic trait. [12] The volatile compound has been used as inhalation rodenticide and human poison, as well as for killing whales. [13] Cyanide ions interfere with iron-containing respiratory enzymes.

COMMENT: Bitter almonds a different species from sweet almonds (what we eat), and are not just bitter, but poisonous. The bitter odor and taste are due to benzaldehyde, but the almonds also contain amygdalin, which when metabolized, releases cyanide. It is possible the bugs release benzaldehyde when disturbed (or crushed), but that does not ...
