I found a bug that was missing since 2006. We found it in a cache that was MIA for about a year but we luckily found it about 40 m away,alittle chewed,wet &moldy .The bug was there but not logged for that cache. We fixed the cache, took the bug to move to the states,where it wants to go and e-mailed the owners,who are from Germany but have not e-mailed us back.So there is always hope for your lost ones.
