Vespula je rod sociálních vos, jehož zástupci jsou rozšíření především na severní polokouli (Eurasie, Severní Amerika). Jsou podobné vosám rodu Dolichovespula, ale mají vertikálně kratší hlavu, častěji hnízdí pod zemí a obecně jsou poněkud agresivnější. Hnízdo bývá zakládáno jen jednou oplodněnou samicí - královnou. Cyklus hnízda trvá od 3,5 měsíců do 8 měsíců, v teplejších oblastech mohou kolonie i přezimovat (hnízdo pak může dosáhnout obřích rozměrů, neboť v něm působí mnoho matek - královen).[1] Dospělci se živí sladkými šťávami, nektarem a medovicí, larvy jsou masožravé a dospělí jedinci pro ně loví rozličný hmyz a další malé bezobratlé. Do rodu Vespula se řadí nejznámější druhy vos a to vosa obecná a vosa útočná. Tyto druhy se staly i invazními živočichy a byly zavlečeny například do Austrálie, Jižní Ameriky, na Nový Zéland či do jižní Afriky.

How To Safely Photograph a Southern Yellowjacket (6241629651).jpg
Autor: Bob Peterson from North Palm Beach, Florida, Planet Earth!, Licence: CC BY-SA 2.0

The Southern yellowjacket (Vespula squamosa) is aggressive and quite dangerous when defending it's nest. Stumbling into the nest flyway or making ground vibrations too close to the entrance can get one swarmed! However, away from the nest while foraging for nectar, insects, rotting fruit and carrion, the yellowjacket is relatively amiable as long as you don't grab or insult her.

Here is one method to safely photograph yellowjackets using an Osprey and a striped mojarra fish (Diapterus plumieri): 1. Befriend an Osprey ("fish hawk") 2. Ask it to go catch a striped mojarra fish (any fish will do). 3. When it is done eating, it will drop it on the ground. 4. Wait while the fish decomposes. 5. Yellowjackets (& flies) will come. 6. Take photographs!

(Or you could just photograph them on rotting fruit but that wouldn't be a challenge :)

This Southern yellowjacket has been drawn to a rotting mojarra fish dropped by an Osprey (there were several yellowjackets and blue bottle flies racing around). Note the two distinctive longitudinal stripes on the mesoscutum (just behind the head) which are characteristic of the species. The wasp is standing on the scales of the fish. The ground nest of these yellowjackets is not far away and has been cautiously and nervously passed by yours truly many times over the last couple of years.

In Nature, Nothing Is Wasted (6263946750).jpg
Western yellowjackets (Vespula pensylvanica), like many insects, act as critical decomposers and nutrient-recyclers. Here, the yellowjackets accomplish these crucial roles as they quickly devour a green bird grasshopper (Schistocerca shoshone).
