today I made with my students some amber investgation; attached four pictures. Am I correct with my expectation about the identity of these flies et al?
(1) a dolichopodid male and ceratopogonid male
(2) smaller ceratopogogonid enlarged
(3) a grooup of three: a spider (web or ground) a dolichopodid and a larva
(4) enlarged a larva of probably beetle (between a grub and leaf beetle)
