The Paederinae are a subfamily of the Staphylinidae, rove beetles. [1] [2] As of 2024, three tribes are accepted within this subfamily: Lathrobiini, Paederini, and Pinophilini. [3] This insect is commonly known as Tomcat. [citation needed]
Cypermethrin is very toxic to cats which cannot tolerate the therapeutic doses for dogs. [6] This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses.
Crushing the beetle also releases the cantharidin. [10] Cantharidin is a poisonous substance which can prove fatal if ingested. The lethal dose for humans when ingested is 10 mg, or 0.5 mg/kg of a human's body weight. The main concern revolves around when the beetle is ingested by livestock, in particular horses. [11]
All parts of the plant contain neurotoxic alkaloids such as isoquinoline and cucullarine, which are known to be poisonous to cats, cattle, and humans. [107] Cattle grazing on the leaves or bulblets may suffer from breathing difficulties, staggering, and convulsions, sometimes fatally. [108] The plant may also cause contact dermatitis if touched ...
O. surinamensis is a slender, dark brown beetle 2.4–3 mm in size, with characteristic "teeth" running down the side of the prothorax. [4] It is nearly identical to Oryzaephilus mercator, or the Merchant Grain Beetle, [2] however, O. surinamensis has smaller eyes and a broader, more triangular head; [2] O. surinamensis unlike O. mercator are unable to fly.
Many other beetles, including ladybirds, blister beetles, and lycid beetles secrete distasteful or toxic substances to make them unpalatable or poisonous, and are often aposematic, where bright or contrasting coloration warn off predators; many beetles and other insects mimic these chemically protected species.

No, Christmas cacti are not toxic to either dogs or cats. If your pet tends to eat houseplants, keep a Christmas cactus out of reach to avoid gastrointestinal discomfort brought on by eating large ...
Diamphidia nigroornata or Bushman arrow-poison beetle, is an African leaf beetle species in the genus Diamphidia. The larvae and pupae of Diamphidia produce a toxin used by San people as an arrow poison. [1] [2] The Finnish explorer Hendrik Jacob Wikar, who travelled in Southern Africa in 1773–1779, described the larvae as "poisonous worms".
