Swarm Caller / Echo Lantern

It's a lantern-like block that emits sounds or echoes that only bugs can hear. We can use it to "attract" bugs and make them float around it to generate certain colored particles like the spore blossom does. It also emits a faint light.

To craft this item, echo shards, glass and copper are needed, and we get a block that works like the jukebox. It would be empty at first because we need a source of sound. 

Instead of a disc, in this case the sound-generating-item could be amethyst/prismarine shards or soul soil. 

This way we get another recipe that uses copper, cave exploration is needed (for the amethyst shards), nether exploration is required (for the soul soil), ocean exploration is recommended (for the primarine shards) and specially this will be a cool reason for us to visit the ancient cities (to get the echo shards).

When you place the echo lantern, the effect activates at night to look just like an opened conduit or the spore blossom, or even an ender chest, so particles that look like fireflies start to float around it and fill the space with ambience particles.

Depending on the sound or echo source used, we might get different types of bugs as they react to the different echo frecuencies only them can hear:

Yellow particles for a caller powered with Soul Soil.
Purple particles for a caller powered with Amethyst shards.
Blue particles for a caller powered with Prismarine shards.
