Background: Of the two known Eupareophora species, more is known about the larva and bionomics of the Nearctic E. parca, than the rarely recorded West Palaearctic E. exarmata.
New Information: The last instar larva and prepupa of E. exarmata is illustrated and briefly described. In Germany its host is Fraxinus excelsior.

Thermal condition affects the development and growth of ectotherms. The stenothermic honeybee brood, particularly the prepupae, are sensitive to low rearing temperature. The fat body plays important roles in energy reserve and metabolism during the honeybee brood development.

Black soldier fly larvae (BSFL) can valorise different organic matter and yield a product of high nutritional value. The lack of knowledge about the microbial safety of BSFL grown on different organic waste streams influences the commercialisation of BSFL as stockfeed ingredient. This study evaluates the microbial safety of BSFL grown on five different commercial food waste streams collected from two commercial production facilities.

Spent mushroom substrate (SMS) is a by-product remaining after harvesting mushrooms. We evaluated the effect of substituting chicken feed with 0-100% of Pleurotus eryngii and Lentinula edodes SMS at different stocking densities (200-1000 larvae/box) on development, composition, and substrate reduction of black soldier fly (Hermetia illucens) larvae. Although the survival rate was not significantly different, feeding pure SMS led to a low growth rate.

Most tortoise beetles, belonging to the subfamily Cassidinae (Coleoptera: Chrysomelidae), possess distinctive explanate margins, comprising elongations of the pronotum and elytra outer margins. These margins flatten against the ground, serving as a unique defensive mechanism against predators. To understand the developmental and evolutionary origins of explanate margins, we examined the development of the pronotal part of these structures in two tortoise beetle species: (Boheman) (tribe Cassidini) and (Boheman) (tribe Aspidimorphini).
