Thank you for your question.
This appears to be the nymphs of the leaf footed bug, a relative of the stink bug. The below is information from the extension:Nymphs of leaf footed bug

These are the nymphs of the leaf footed bug, a relative of stink bugs. Adult leaf footed bugs are brown, with a flattened, leaf-shaped area on their hind legs. Both the nymphs and adults are pests that damage buds, flowers, fruits and seeds. Leaf footed bugs feed on many plants, including tomatoes, peaches, blueberries, beans, okra, and pecans. When these bugs feed on tomato fruit, they cause yellow, hardened spots to develop. Feeding on other fruits can cause brown spots to shriveled, misshapen fruits, depending on the number of bugs and the time the fruits are damaged.

Adult leaf footed bugs overwinter in weedy areas or under mulch and debris. They lay eggs in a row on the undersides of leaves or on stems. Eggs hatch in 5-7 days, and nymphs mature in 25-30 days.

Leaf footed bugs and their stinkbug relatives are difficult to control, but scouting for these pests now will help keep populations from building up throughout the season. Removing the nymphs and adults by hand and dropping them into a container of soapy water is an effective means of control when populations are small. You may want to wear gloves when picking leaf footed bugs from your plants – they do have an unpleasant smell. There are few organic pesticides that are effective on these bugs, but hand picking now and reducing places where the adults can overwinter will help keep next year’s population in check. If you choose to use an insecticide to control a large population of leaf footed bugs, pyrethroids can be used as directed.

Just a quick word of caution, though – some assassin bugs (beneficial insects) are also orange and can look similar to the leaf footed bug nymphs shown above. For photos of assassin bugs, click here
