Apiomorpha urnalis is a woody gall produced by a parasitic hemipteran. The female inside the large gall remains physically underdeveloped and never independent of her host plant. The dissection shows the larviform adult female.
This gall forming scale bug (Apiomorpha munita, family = Eriococcidae) produces a chemical stimulant causing the plant to grow a protective cage. The smaller posterior structures are (empty) male galls. The dissection shows the adult female prisoner with reduced wings, legs, antennae etc.
