Female galls on Yellow Box. Counted at least 40 on a 2m high sapling. Almost all straight sided, just a few more bulbous. The longest was 20mm. Bulbous gall in the photo is 16mm long and about 6mm diameter.
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.
