Bdellodes

Coccinella septempunctata
seven-spot ladybird, seven-spotted ladybug, seven-spotted lady beetle, C-7
Coccinella septempunctata is a predatory lady beetle native to Europe, Asia, and North Africa, now widely established in North America following intentional introduction for biological control. Adults measure 6.5–7.8 mm with distinctive red elytra bearing seven black spots. The species is among the most extensively studied coccinellids due to its importance in aphid biocontrol and its invasive success in new ranges. It completes up to five generations annually with a six-week development cycle from egg to adult.

Inostemma is a genus of minute parasitoid wasps in the family Platygastridae, established by Haliday in 1833. Species within this genus are known to parasitize gall midges (Diptera: Cecidomyiidae) across diverse habitats including pine forests, agricultural crops, and tropical vegetation. Several species have been documented as biological control agents of pestiferous gall midges, with well-studied examples including parasitoids of the invasive pine needle gall midge in eastern Asia. The genus exhibits cosmopolitan distribution with particular diversity in the Palearctic, Asia, and Madagascar.
Nabis vanduzeei
Nabis vanduzeei is a species of damsel bug in the family Nabidae, a group of small predatory true bugs. Like other members of the genus Nabis, this species is a nocturnal predator that subdues insects often larger than itself using raptorial forelegs. The species is documented from limited observations, with 14 records on iNaturalist. Damsel bugs in this genus are economically significant as biological control agents in agricultural systems.
Omalodes
clown beetles
Omalodes is a genus of clown beetles in the family Histeridae, comprising approximately 63-68 described species distributed across three subgenera. It represents the largest genus within the tribe Omalodini and has an exclusively Neotropical distribution, with some species extending into the southern United States. One species, Omalodes (Omalodes) fassli, has been reported on banana crops in Colombia where it may play a role in controlling the banana weevil. The genus is characterized by morphological features including complete apical stria on the elytra in some subgenera.
