Yes, the identification of certain arthropods is not easy, so there are many species that despite being discovered, still do not have data that place them in a particular family or genus, others are initially placed in some group and after new discoveries move them to another. Sometimes it takes me more than a month to prepare an arthropod specimen for a post, especially if I include the whole phase of its development from egg to adult, this can be seen in some of the publications I have on butterflies and moths.
On the other hand, the bedding that the spider makes to protect its eggs is very similar to cotton, it uses several layers of webbing. Interesting about your granddaughter's school emblem, will she be studying something related to biology? Thanks so much for your support! Regards.
