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]
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]
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.
Chrysochus cobaltinus, the cobalt milkweed beetle or blue milkweed beetle, is a member of the diverse family of leaf beetles, Chrysomelidae. It is named after its cobalt-blue exoskeleton , which makes it easy to spot and distinguish, and its tendency to feed off milkweed plants.
Larvae go through two instars before pupation. Both larvae and adults are predatory on other insects. [3] Because of their preference for moist soil, large numbers of Paederus beetles may be attracted to irrigated farmland, where they provide some benefit by eating herbivorous insects but can cause problems for people working in fields or ...
Due to cats' natural hunting instinct, their ability to adapt to different environments, and the wide range of small animals they prey upon, both feral and free-ranging pet cats are responsible for predation on wildlife, and in some environments, considerable ecological harm. Cats are disease carriers and can spread diseases to animals in their ...
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 ...
When the beetle senses some form of disturbance that requires a defensive mechanism, the beetle will secrete the cardenolides, poisoning its enemies. [4] This mutation may explain the dogbane beetle's insensitivity to the poisonous compounds, especially because this same mutation has been shown in the cardenolide-insensitive monarch butterfly .
