Hectic is a period-30 oscillator found by Robert Wainwright in September 1984.[1] It consists of two gliders shuttled in a loop between four queen bees. Similar but larger loops can be constructed.

While the reaction used in the oscillator is a compact way to reflect a p30 glider stream, it is not very convenient since the queen bee also relies on the glider for survival, and therefore gaps in the glider stream will destroy the shuttle. The stable buckaroo is more versatile. Another reliable one is stabilising this with another queen bee shuttle head-on to destroy the beehive just before the reflecting queen bee arrives, as can be seen in the following p30 glider duplicator:
