spotted lanternflies on branch
Not all species that arrive someplace new survive and prosper. New colonies are begun by a limited number of individuals, so the resulting gene pool is small, potentially limiting adaptability or fitness due to inbreeding. Females that produce offspring from multiple fathers, however, can help maintain a robust gene pool. Researchers at Temple University recently investigated the role of multiple paternity—individuals from more than one father in the same egg mass—in spotted lanternflies (Lycorma delicatula).
