German Yellowjacket

Fascinating facts about the German Yellowjacket

• A German wasp never flies farther than a kilometre on its own, yet it still colonises new continents. For a given year, V. germanica disperses at distances of no more than 1000 m, (1 km) so that their rapid dispersal is likely to be aided by accidental human transport of hibernating queens. This normally leads to a bottleneck effect during the establishment of new populations, which explains the significant genetic differentiation often found among geographically distant populations.
• A German wasp colony can swell to tens of thousands in warm climates. V. germanica nests are strongly affected by climate. Average colonies in Australia contain over 9500 small workers and 3600 large queen and male cells. By the end of May, colonies in Australia have 15,000 wasps emerging from small cells and 2500 wasps emerging from the large cells. By comparison, nests in the British Isles only have 6100-6500 small cells and 1500 large cells on average, in roughly eight combs.
• A German wasp worker often juggles several jobs in a single day. Approximately 61 percent of the wasps observed perform more than two of these tasks during their lifetimes. Additionally, about 40 percent of the wasps specialize on only one task per day, but these individuals varied with respect to age and sequence of task performance. The schedule of temporal polyethism found in V. germanica is highly accelerated when compared to other Hymenoptera, which is likely related to worker lifespan.
• A German wasp colony police's its own workers so efficiently that almost all rogue male eggs disappear before hatching. This is demonstrated by a study carried out in Belgium, showing that while an estimated 58.4 percent of male eggs were laid by workers, only 0.44 percent of adult males were workers' sons. The numbers indicate the efficiency with which worker policing is carried out, protecting colony productivity and maintaining the expected sex ratio.
• The German wasp is about 13 mm (0.5 in) long, has a mass of 74.1 ± 9.6 mg, and has typical wasp colours of black and yellow.
