This is something that I have not recorded for quite some time, but will start doing again. Taking the head measurment of larvae is the safest way to determind which larval stadium the larva is in, more than the weight.
Some of the head sizes of beetle larvae are given here. I think it will help beginners to find out in which stage their larvae are. Surplus it is interesting data in order to compare it with the sizes of one’s own breeding and to see what size of imagos could be reached by the different larvae. The data is taken from larvae that moulted into normal sized imagos. The measure was taken from eye to eye. (<—>)

Cant find my female Prosopocoilus astacoides blanchardi at all. I put the male and female in a soil box with a chunk of the wood that the female lays her egg in. When I took the wood out, there was a oval shaped hole in it. Is it inside?
Please reply ASAP

P.S. I’m human. Just using number names for safety.
Hi there,
actually, that might be a good sign. if you cannot find her anywhere and if there are no other options for her to escape. PLus if she chewed a hole into he wood is also a good sign, even though it is kind of unusual for them to dig in entirely into the wood π
Hope that helps π
