Document Summary
Aculeata stinging wasps: modified ovipositor, specifically; eggs laid from near base of ovipositor (not at tip), the tip delivers potent venom for host/prey capture and defense (against larger. Modified ovipositor + ve(cid:374)o(cid:373) called the sting, or the stinger. Basal taxa are ectoparasitic idiobionts; derived taxa are eusocial: 40,000 species (many ants undescribed) Evolved independently multiple times within aculeata general characteristics: insects live in a colony; protected in substrate or nest: division of labor among castes, 1. Non-reproductive worker caste working on behalf of 2. Reproductive caste: can be a third soldier caste, cooperation in caring for young, only the queen lays eggs, castes within a species have diff morphologies; caste polymorphism eg. european honey bee. Eusociality: reproduction: each colony produces new queens and males during life cycle of colony, nuptial flight: 1. Neighboring colonies synchronize release of new queens and males; environmental cues 2.
