Fruits of Ilex Integra (Elegance Female Holly)? モチノキの実？

Japanese follows English. 英語の後に日本語が続きます。

These "may be" the fruits of Ilex integra or more commonly the elegance female holly or mochi tree at the Tokyo National Museum. I said "may be" because I'm not sure...

Many of the fruits were scattered on the ground before turning red. The unusual weather may be why. This year, the rainy season ended in late June, nearly one month earlier than usual and it became extremely hot. Then the rainy weather came back.   

Looking at these fruits made me (wrongly😅) feel autumn was coming for a second until I found several mosquitos biting me🦟. The real summer has yet to come...

Ilex Integra (Elegance Female Holly) モチノキ

Japanese follows English. 英語の後に日本語が続きます。

These are the fruits of ilex integra or elegance female holly. They're 1 cm in diameter, and some are red while others still green for a reason.  

The tree has a natural enemy, i.e., a wasp "macrodasyceras hirsutum Kamijo." The baby wasps lay eggs within ilex integra seeds in summer, and in autumn, the wasp larvae stop the fruit changing from green to red (wow!) to prevent the red ripe fruits from being eaten by birds, which usually eat red fruits, spreading the seeds around and helping the plants' reproduction.

These green fruits may be naturally green or stopped by the larvae from turning red, but either way, ilex integra and the wasp both are fighting for their survival.
