1. Some caterpillers just don't want to grow up
   03-16-2007 · EurekAlert!
   An international project explores why it's an evolutionary advantage that only 25 percent of the caterpillars of Maculinea rebeli, a Lycaenid butterfly whose caterpillars live as parasites inside colonies of Myrmica ants, feeding on regurgitations from the nurse ants, complete development within one year. The rest are inactive and mature after two years. Intense competition and years where the ant colony avoids reinfection may be part of the explanation.

3. Scientists discover molecular basis of monarch butterfly migration
   01-07-2008 · EurekAlert!
   An ancestral circadian clock mechanism is defined in monarch butterflies, in which two CRYPTOCHROME proteins function as critical components. The proteins may also function as output molecules that connect the clock to the sun compass for successful navigation.

4. Unpeaceful co-existence: How strengths and weaknesses maintain biodiversity in an ant community
   02-08-2007 · EurekAlert!
   Many species of ants scavenge for the same food, but the single most efficient species doesn't drive the others to extinction. Adler et al. modeled this unpeaceful co-existence. Some species are better at finding food while others are better at defending it. Some ants are efficient at both but flee when their own enemies (parasitoid flies) arrive.

7. Wood ant queen has no egg-laying monopoly
   06-27-2007 · EurekAlert!
   Insect queens were thought to have an egg-laying monopoly, but nine wood ant species revealed widespread reproductive activity by worker ants. Genetic analysis showed that as many as one in four eggs were laid by workers. Workers in many insect species can lay unfertilized male eggs, but usually workers in large colonies enforce the exclusive reproduction of the queen.

9. Study links success of invasive Argentine ants to diet shifts
   12-17-2007 · EurekAlert!
   The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.
