The slime mold life cycle includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies that may be formed through aggregation or fusion; aggregation is driven by chemical signals called acrasins.
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".
Reproduction in this species happens when adult beetles emerge throughout Spring and lay eggs in deadwood. [5] Research around sexual behaviours and courtship of Clytus arietis is quite dated, with many sources from the 1960s. A paper from 1963 states that both male and female wasp beetles engage in a "courtship song", without offering further ...
Female M. melolontha Beetle. Adults appear at the end of April or in May and live for about five to seven weeks. After about two weeks, the female begins laying eggs, which she buries about 10 to 20 cm deep in the earth. She may do this several times until she has laid between 60 and 80 eggs. Most typically, the female beetle lays its eggs in ...
Ambush bugs – subfamily Phymatinae Thread-legged bugs – subfamily Emesinae , including the genus Emesaya Kissing bugs (or cone-headed bugs) – subfamily Triatominae , unusual in that most species are blood-suckers and several are important disease vectors
Burying beetle life cycle. The prospective parents begin to dig a hole below the carcass. While doing so, and after removing all hair from the carcass, the beetles cover the animal with antibacterial and antifungal oral and anal secretions, slowing the decay of the carcass and preventing the smell of rotting flesh from attracting competition. [2]
The drugstore beetle prefers warmer temperatures so placing them in a freezer for either 16 days at −2 °C or 7 days at −25 °C will kill them at any stage in their life cycle. Alternatively, the beetles can also be heated at extremely high temperatures of 88 °C for an hour or 48 °C for 16 to 24 hours in an oven.
The life cycle of burying beetles offers a vivid illustration of this equilibrium, with juvenile hormone levels experiencing a surge as larvae emerge—a phase coinciding with a noted decrease in PO levels. However, research indicates that PO levels can be upregulated in response to injury, even as larvae partake in feeding on the carcass.
