I will confirm everything Paul says, and add one note for US members of 
the list: I am aware of only ONE price catalog that lists and gives a 
value for all insects of all orders and families, from earwigs to 
psychodids to mymarids to lice - the BioQuip specimen catalog, at

There is no insect in this catalog that costs less than $3, so if you 
donate more than 1666 specimens in a year, you will exceed the $5000 
cutoff for a non-appraised donation.

Unless your donation is smaller than 1666 specimens, therefore, there is 
no point in trying to look up the prices species by species, or trying 
to factor in pins or other costs. I recommend to simply claim $4999, and 
state on Form 8283 that you are claiming *less* than the fair market 
value of donated specimens (that way, you stay below the 5K cap and 
avoid an appraisal). The IRS, in my experience, has no issue with people 
claiming *smaller* deductions than they are entitled to.
