ive built a small incubator with a heat mat and i put the three large ones (3-5 cm) into cups filled with a compost/coco fibre/sand mixture and gave them fish flakes and bee pollen but it immediately molded.

im now considering either having them without any substrate as i saw in a 2024 yt video by bugsnstuff, or to keep them in organic substrate but not give them any food that would mold immediately. idk what the better course of action would be because i dont know wether they are really ready to pupate yet.

or do they really just start to pupate once they are in the incubator?

TLDR: food but no substrate, substrate but no food, or is there a way to keep food from molding on substrate?

thx

i found unexpectedly large larvae in my terrarium after having almost given up on offspring when the only male died. these look to be almost ready to pupate. what do i need to do??

very obviously shows that shrews are not rodents

Die flaschen haben alle die selbe Form, aber ein Kasten 0,3L Bionade passt nicht auf einen Kasten 0,3 Fritz Limo, und ein Kasten 0,5 Sterni passt nicht auf einen Kasten 0,5 Bitburger... was soll die scheiße? Warum sind ausgerechnet die nicht genormt?? das is doch bestimmt ein Albtraum für jeden Getränkehändler.

a goose barnacle descendant that evolved to actively hunt fish and other marine animals with modified raptorial cirri. They started out as facultative ambush predators but evolved to detach from the substrate and swim using a modified peduncle convergently having evolved a whale like tail. the first pair of cirri evolved into sensory structures with chemoreceptive and tactile function. the rudimentary nauplius eye and lateral eyes have undergone rapid evolution, becoming true (simple) eyes, uniquely three seperate ones, giving the barnacle remarkable 3D vision. one pair of cirri evolved to resemble pectoral fins, and have a similar function. Their life cycle is pretty similar to other barnacles, with a nauplius and cyprid stage, but with the exception that the barnacle detaches from the substrate after the first molt.

i really like this because the barnacle is dorso-ventrally as well as anterior-posteriorly switched compared to other crustaceans, somewhat convergently evolving the deuterostome condition.

still looking for a name. suggestions welcome

like is there a reason why convergent structures couldn't or wouldn't be like in the bottom picture? having them curl upwards seems cumbersome for some reason bit i can't think of a reason why it would be implausible. underwater gravity wouldn't be much of a factor so that's not it.

found in a wasp in Germany. also the head and prothorax of a male

the smaller wasp is infected by a strepsipteran too which is cool.

Weird nest cluster thing I found in Germany. Looks like a huge amount of pupa husks in a large mat of fibrous stuff and granules of something dirt like. Like half a meter long. i guess some kind of fly or moth? what is this??

since last week ive seen them tease each other with their antennae. the only male died last summer... they are behaving just like he did... are they just gay?
