The representative families are Dryopteridaceae, Athyriaceae, Polypodiaceae, Thelypteridaceae, Selaginellaceae and Aspleniaceae. The main genera are Dryopteris, Selaginella, Asplenium, Arachniodes, Pteris, Allantodia and Plagiogyria. The top families' distribution types are cosmopolitan and pantropic ones, the main genera are pantropical ones, while species distribution type belong to the east Asia type and represents the feature of subtropics transition to warm temperated areatype. As for the order of closeness, the sequence of pteridophytes floristic relations between Songyang and the adjacent regions goes as Southwest China, South China, Central China, Japan, North China, Northwest China and Northeast China. The six upland pteridophytes next to Songyang can be put into the same natural flora because of its closest relationship. But compared with other 11 upland fern flora in China, fern in Songyang is not rich enough. There are 37 species endemic to China in Songyang.

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.
