| 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. |
