| Parasitic wasp larvae grow inside a caterpillar, Large White,
|| Pieris brassicae. On emerging, larvae make cocoons nearby.
|| Parasitic wasps, Apanteles glomeratus, emerge from cocoons
|| An emerged Apanteles glomeratus near more cocoons
|| Apanteles glomeratus makes fluffy yellow cocoons 3mm long
|| Microscope shows empty Apanteles glomeratus cocoon x 40
| Two caterpillars of Large White Butterfly, Pieris brassicae
|| Spider has eaten pupating Apanteles glomeratus
|| Outside on the shed roof more caterpillars are climbing in
|| from the apple tree above (how did they get there?)
|| Caterpllars under the shed roof are safer than outdoors ...
|| ... for pupating, but the wasp finds them anyway.
| This chrysalis of Pieris brassicae may have escaped,
|| but another wasp, Pteromalus puparum, probably ate this one.
